Remote photoplethysmography system for unsupervised monitoring regional anesthesia effectiveness
2017
Determining the level of regional anesthesia (RA) is vitally important to both an anesthesiologist and surgeon, also knowing the RA level can protect the patient and reduce the time of surgery. Normally to detect the level of RA, usually a simple subjective (sensitivity test) and complicated quantitative methods (thermography, neuromyography, etc.) are used, but there is not yet a standardized method for objective RA detection and evaluation. In this study, the advanced remote photoplethysmography imaging (rPPG) system for unsupervised monitoring of human palm RA is demonstrated. The rPPG system comprises compact video camera with green optical filter, surgical lamp as a light source and a …
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…

Innovative Managed Care May Be Related to Improved Prognosis for Acute Myocardial Infarction Survivors
2021
Background: Mortality following discharge in myocardial infarction survivors remains high. Therefore, we compared outcomes in myocardial infarction survivors participating and not participating in a novel, nationwide managed care program for myocardial infarction survivors in Poland. Methods: We used public databases. We included all patients hospitalized due to acute myocardial infarction in Poland between October 1, 2017 and December 31, 2018. We excluded from the analysis all patients aged <18 years as well as those who died during hospitalization or within 10 days following discharge from hospital. All patients were prospectively followed. The primary end point was defined as death …
The effect of conventional movement training and trampoline training on balance and gait in chronic hemiplegic patients
1991
The postural sway of subjects during standing both with their eyes open and closed together with maximum velocity of walking were analysed in six male chronic hemiplegic patients before, during and after an intensive movement training programme lasting 8 weeks. The movement training programme was carried out on the basis of Bobath's principles. Three of the subjects carried out their training on a trampoline, with the particular purpose of enhancing the stimulation of the mechanisms responsible for the control of balance. During the follow-up, maximal walking velocity remained at previous levels and no systematic changes were observed in the control of postural sway. Although the use of the…
Imaging photoplethysmography for assessment of chronic pain patients
2019
In present pilot study application of multi-spectral imaging photoplethysmography for assessment of chronic pain patients during topical skin heating test was proposed. Photoplethysmography signal was recorded at 420nm, 530nm and 810nm illumination from the skin and corresponding perfusion indexes and perfusion maps were calculated. The novel parameter-PPGflare index was introduced and compared in neuropathic patients and healthy volunteers. Preliminary results suggest that neuropathic patients exhibited significantly lower PPGflare index, and that local heating substantially change PPG waveform at heat exposed skin region. Present study emphasizes advantages of imaging photoplethysmography…
<title>Potential of advanced photoplethysmography sensing for noninvasive vascular diagnostics and early screening</title>
2002
Advanced sensor device for shape analysis of the tissue- reflected mean single period photoplethysmography (SPPPG) signals has been designed and clinically tested. The SPPPG signal shape reveals individual features of the patient's cardio-vascular state. Clinical studies of several patient groups (e.g. diabetes mellitus, atherosclerosis obliterans, Raynaud's syndrome) made possible to specify components of the SPPPG signal that are sensitive to the corresponding organic or functional pathologies. Comparison of the right and left arm finger SPPPG signal shapes, for instance, appears to be efficient tool for early screening of unilateral atherosclerosis obliterans.© (2002) COPYRIGHT SPIE--The…
Health Tecnology Assessment: bisogni formativi teorici e pratici nelle Scuole di Specializzazione in Igiene e Medicina Preventiva
2010
Objective: The aim of our study was to perform a survey of Italian graduate students (medical doctors) attending Public Health Schools, in order to assess the importance and training needs concerning Health Technology Assessment (HTA) during their public health postgraduate education. Methods: In July 2010, we sent by e-mail a questionnaire to all graduate medical students attending Public Health Schools from four Italian Regions (representing Northern, Center and Southern Italy). The questionnaire included two sections: 1) knowledge on HTA; 2) assessment of the importance of HTA training during academic public health education. Main results: Eighty-two Public Health graduate students from …
Unmet needs in the management of schizophrenia
2014
Studies on unmet needs during the last decades have played a significant role in the development and dissemination of evidence-based community practices for persistent schizophrenia and other severe mental disorders. This review has thoroughly considered several blocks of unmet needs, which are frequently related to schizophrenic disorders. Those related to health have been the first block to be considered, in which authors have examined the frequent complications and comorbidities found in schizophrenia, such as substance abuse and dual diagnosis. A second block has been devoted to psychosocial and economic needs, especially within the field of recovery of the persistently mentally ill. Wi…
Usability of photoplethysmography method in estimation of conduit artery stiffness
2011
Three channel photoplethysmography (PPG) signal waveform studies of leg conduit arteries during a provocative occlusion test were performed. PPG waveform second derivative amplitude ratio and arterial pulse wave velocity values showed significant correlations with ultrasound (US) reference method of local and regional arterial stiffness (AS), showing the ability to use PPG for AS change quantitative assessment.
