Diabetes Interactive Diary: A New Telemedicine System Enabling Flexible Diet and Insulin Therapy While Improving Quality of Life
2009
OBJECTIVE Widespread use of carbohydrate counting is limited by its complex education. In this study we compared a Diabetes Interactive Diary (DID) with standard carbohydrate counting in terms of metabolic and weight control, time required for education, quality of life, and treatment satisfaction. RESEARCH DESIGN AND METHODS Adults with type 1 diabetes were randomly assigned to DID (group A, n = 67) or standard education (group B, n = 63) and followed for 6 months. A subgroup also completed the SF-36 Health Survey (SF-36) and World Health Organization-Diabetes Treatment Satisfaction Questionnaire (WHO-DTSQ) at each visit. RESULTS Of 130 patients (aged 35.7 ± 9.4 years; diabetes duration 1…
Effectiveness of a physiotherapy and nutrition program in patients with coronary artery disease: randomized controlled trial
2021
Abstract Funding Acknowledgements Type of funding sources: None. Introduction. Dietary and exercise interventions are effective strategies for improving physical and nutritional status of patients with coronary artery disease (CAD). However, few studies have applied a combined exercise protocol based on high intensity interval training (HIIT) and dietary education in patients with CAD with percutaneous coronary intervention (PCI). Purpose This study researches the effectiveness of a multidisciplinary program based in HIIT with dietary education (DEHIIT) in comparison with only HIIT, on adherence to Mediterranean diet in CAD patients with PCI. Methods. A prospective, assessor-blinded, parall…
Brain Natriuretic Peptide and Discovery of Atrial Fibrillation After Stroke
2020
Background and Purpose— Diagnosing paroxysmal atrial fibrillation (pAF) can be challenging after acute ischemic stroke. Enhanced and prolonged Holter-ECG monitoring (EPM) improves the detection rate but is not feasible for all patients. We hypothesized that brain natriuretic peptide (BNP) may help to identify patients with stroke at high risk for pAF to select patients for EPM more effectively. Methods— Patients with acute cerebral ischemia ≥60 years presenting in sinus rhythm and without history of AF were included into a prospective, randomized multicenter study to receive either EPM (3× 10-day Holter-ECG) or usual stroke care diagnostic work-up. BNP plasma levels were measured on random…
Cognitive Behavioral Therapy Versus Sertraline in Patients With Depression and Poorly Controlled Diabetes: The Diabetes and Depression (DAD) Study
2015
OBJECTIVE This study compared the long-term efficacy of a diabetes-specific cognitive behavioral group therapy (CBT) with sertraline in patients with diabetes and depression who initially responded to short-term depression treatment. RESEARCH DESIGN AND METHODS A randomized controlled single-blind trial was conducted in 70 secondary care centers across Germany comparing 12 weeks of CBT with sertraline in 251 patients with type 1 or 2 diabetes (mean HbA1c 9.3%, 78 mmol/mol) and major depression (Structured Clinical Interview for DSM-IV [SCID]). After 12 weeks, treatment responders (≥50% reduction Hamilton Depression Rating Scale [HAMD-17]) were included in the 1-year study phase where CBT p…
Multidisciplinary program based in physiotherapy and nutrition in coronary artery disease patients: randomized controlled trial
2021
Abstract Funding Acknowledgements Type of funding sources: None. Introduction. The interventions on eating habits and exercise in physiotherapy programs are usually recommended in coronary artery disease (CAD), since they are beneficial to improve physical and nutritional status of patient. Despite this, scarce studies are focused on combined protocols based on high intensity interval training (HIIT) and dietary education in CAD patients with percutaneous coronary intervention (PCI). Purpose The main goal of this study was to compare the effectiveness of a multidisciplinary program based in HIIT, with a program based in dietary education and HIIT (DEHIIT), on eating habits in CAD patients w…
Impact of a program based in eating habits and physiotherapy on anthropometric parameters in patients with coronary artery disease: randomized contro…
2021
Abstract Funding Acknowledgements Type of funding sources: None. Introduction. On the one hand, physical training such as High intensity interval training (HIIT) and on the other, eating habits, it is often prescribed to patients with coronary artery disease (CAD). Nevertheless, the combination of HIIT and eating habits in CAD with percutaneous coronary intervention (PCI) there is no consensus on using a combined protocol of both. Purpose. The purpose of this study was to evaluate the impact of an HIIT program with eating habits, with a program based in HIIT, on anthropometric parameters in CAD patients with PCI. Methods. A randomized controlled trial was carried out in a hospital. 44 pati…
Robust consensus in social networks and coalitional games
2014
We study an n-player averaging process with dynamics subject to controls and adversarial disturbances. The model arises in two distinct application domains: i) coalitional games with transferable utilities (TU) and ii) opinion propagation. We study conditions under which the average allocations achieve robust consensus to some predefined target set.
Modulation of La Crosse virus infection in Aedes albopictus mosquitoes following larval exposure to coffee extracts
2013
This commentary highlights key points, basic ideas, and future outlooks presented by Eastep et al. (2012) in Frontiers in Physiology-Systems Biology. The authors have provided an interesting investigation about the successful use of an environmentally friendly product derived from plants as a larvicidal agent to control mosquito populations as well as a substance that could alter the vector competence of mosquitoes for arthropod-borne viruses (arboviruses). Specifically Eastep and collaborators used coffee extracts (with and without caffeine) to try to answer two hypothesis: first, coffee extracts could have good results as a mosquitocidal compounds applied in larval biotopes and second, vi…
A robust aerial image registration method using Gaussian mixture models
2014
Aerial image registration is one of the bases in many aerospace applications, such as aerial reconnaissance and aerial mapping. In this paper, we propose a novel aerial image registration algorithm which is based on Gaussian mixture models. First of all, considering the characters of the aerial images, the work uses a shape feature detector which computes the boundaries of regions with nearly the same gray-value to extract invariant feature. Then, a Gaussian mixture models (GMM) based image registration model is built and solved to estimate the transformation matrix between two aerial images. Furthermore, the proposed method is applied on real aerial images, and the results demonstrate the …
TAKEOFF AND LANDING ROBUST CONTROL SYSTEM FOR A TANDEM CANARD UAV
2005
In spite of modern wide improvements in UAV’s technologies, a few number of such a vehicles is fully autonomous from takeoff to landing . So, either autonomous operation or operation with minimal human intervention is, actually, the primary design goal for the UAV’s researchers. The core of the problem is the design of the landing and takeoff control system. The objective of this paper is to design a control system in which the same state variables are controlled during both the descending/ascending path and the flare, tacking into account the actual ground effect. Robust control techniques are employed with the aim to cope with atmospheric turbulence, measurement noise, parameter variation…
