Childhood overweight and obesity are related to cardiovascular risk (CVR) factors (hypertension, type 2 diabetes mellitus, abnormal lipid profiles and increased risk of adult obesity and high morbidity and mortality rates. Methods: We performed a retrospective study of 78 overweight and obese children, hospitalized in a Pediatric Clinic from Saint Mary Hospital Iasi, 42 girls and 37 boys. The nutritional...
The cardiovascular system is regulated by the autonomic nervous system, under cortical modulation. Stroke can induce cardiac autonomic imbalance, therefore, causing secondary cardiovascular complications. Heart rate variability (HRV) analysis is a simple method to appraise the autonomic nervous function. The purpose of this study was to investigate the cardiac autonomic activity in patients that suffered...
This paper presents the implementation of a research project focused on the use of robotics as an effective tool in teaching technical disciplines to dyslexic children. Dyslexia is the most common learning disability and affects between 5 and 12 percent of all students. The goal of this project is to develop educational programs which will boost school performance of dyslexic children by using robotics...
QT prolongation has been associated with arrhythmias and sudden cardiac death, but despite this it has been less studied among patients with Alzheimer's disease and vascular dementia. For measuring QTc we have used the new criteria of American Heart Association Electrocardiography and Arrhythmias Committee. There were no significant differences in QTc, values between Alzheimer's disease patients and...
In this paper we studied the influence of electromagnetic wireless communications traffic on sensitive medical equipment used in intensive care units. We have identified the main sources of disruptive electromagnetic field existing in a neonatal intensive care unit and studied the influence of wireless communication systems type GSM and DECT 900 on the main operating parameters set to a neonatal mechanical...
In this paper cardiovascular variability has been evaluated in patients with cerebrovascular accident (CVA), in patients recovering from stroke. In this prime report, more than twenty patients were examined; time-domain and frequency-domain parameters were studied during deep breathing (DB), Valsalva maneuver (VA) and hand grip (HG). After this we compared the HRV obtained in the specific test for...
The growth of micro-organisms on a culture medium for the biosynthesis of products is the process of interaction of the individual cell and culture medium. Applying the laws of thermodynamics and mass transfer and energy demonstrates that culture of microorganisms is influenced directly the temperature, pH and concentration of substrate. Implementation of monitoring and management favorable methods...
This paper presents a design of medical device for bioelectrical impedance estimation. The hardware required to implement the system is based on a signal generator to provide current, a microcontroller to coordinate the process and a data acquisition board to measure the voltage changes across the analyzed region. The algorithm for calculating the physiological variables was implemented in MATLAB...
This article aims at assessing the involvement of the peripheral nervous system for patients with ischemic pathology of the lower limbs. We studied relationships between the ankle brachial index and peripheral nerve function among 60 male patients with peripheral arterial disease (PAD). The ankle brachial index was measured using a handheld Doppler probe. Nerve function was measured in the motor fibres...
Medical technology is by now an integral part of health care according to consisting general accepted standards. The Medical Equipment Management Plan defines the mechanisms for interaction and oversight of the medical equipment used in the diagnosis, treatment, and monitoring of patients. The related policies and procedures govern activities from selection and acquisition to incoming inspection and...
Medical equipment risk assessment is part of an overall medical equipment management program for a healthcare facility or system. A complete program includes corrective maintenance or repair, equipment control, asset management, health care technology planning, education, and activities directed toward improving medical device-related patient safety. The purpose of this paper is to provide some guidance...
Electrical impedance method has found utility in many fields of medical research, but the old instrumentation can be expensive to use and complicated to build. Advancements in electronic component design and equipment allow a bioimpedance analysis using a simple medical device. The aim of this work is to design a medical device which estimates the blood flow and calculates some hemodynamic parameters...
Nowadays in most European countries the health systems are pressed by massive requests for assisting a growing number of people suffering from chronic diseases. The present work refers to an e-Health monitoring system dedicated to patients with chronic diseases. The system includes a medical device for monitoring some vital parameters on patients that alongside a software application, it provides...

The aim of this study was to acquire non - invasively and to analyze plethysmographic waves, by measuring the electrical impedance of a peripheral segment. For measurements we built a device that is designed as an injection module with a microcontroller which generates a sinusoidal pulse with adjustable frequency (10–200 kHz) and adjustable intensity. In output, the device delivers an analoge signal...
