This paper presents a system for classification of asthma based on artificial neural network. A total of 1800 Medical Reports were used for neural network training. The system was subsequently tested through the use of 1250 Medical Reports established by physicians from hospital Sarajevo. Out of the aforementioned Medical Reports, 728 were diagnoses of asthma, while 522 were healthy subjects. Out of the 728 asthmatics, 97.11% were correctly classified, and the healthy subjects were classified with an accuracy of 98.85%. Sensitivity and specificity were assessed, as well, which were 97.11% and 98.85%, respectively. Our system for classification of asthma is based on a combination of spirometry (SPIR) and Impulse Oscillometry System (IOS) test results, whose measurement results were inputs to artificial neural network. Artificial neural network is implemented to obtain both static and dynamic assessment of the patient's respiratory system.

This paper presents the results of a study developing artificial neural network system (ANN) for classification of Alzheimer's disease (AD) and healthy patients. The classification is done using biomarkers, from cerebrospinal fluid: albumin ratio (CSF/Serum and/or Plasma), Aβ40 (CSF), Aβ42 (CSF), tau-total (CSF) and tau-phospho (CSF). Neural network input parameters are datasets from Alzbiomarkers database. Independent t-test is used to calculate statistical difference between input parameters. Developed neural network was validated with 80 subjects from Alzbiomarkers database. Out of 45 AD subjects, 43 were correctly classified as AD patients, obtaining a sensitivity of 95.5%, and out of 35 healthy subjects 32 were correctly classified obtaining specificity of 91.43%.

Samples are obtained from subjects using Pasco sensors in 7D cinemas. Out of 77 samples, in 71% of subjects higher level of stress is recognized, while 29% of subjects are classified as subjects with normal vital functions. An accuracy of 99% and specificity of 98% is obtained.

This paper presents a system for prediction of naphthalene concentration in the liver and lung compartments of a micro cell culture analog apparatus (μCCA) based on the Artificial Neural Network (ANN). The implemented ANN can be used to simulate organ and circulatory system reactions in terms of residual naphthalene concentrations. For neural network training, 100 samples were used and additional 100 samples were used for subsequent validation. For the lung compartment, the accuracy of prediction of naphthalene concentration is 97% and the accuracy of concentration prediction in liver compartment is 95%. Implemented neural network for prediction of residual concentration of naphthalene in lung and liver compartments of a μCCA uses the fraction of exiting stream that re-enters the microcircuit as input value. This system can be used for simulating the organ and circulatory system reactions before conducting experiments on micro cell culture analog apparatus.

This paper presents a system for classification of asthma based on fuzzy rules. Fuzzy rules are defined according to Global Initiative for Asthma (GINA) guidelines, as well as through consultations with long-term experience of pulmologists. Our fuzzy system for classification of asthma is based on a combination of spirometry (SPIR) and Impulse Oscillometry System (IOS) test results, which are inputs to fuzzy system. Additionally, the use of bronchodilatation and bronhoprovocation enabled a complete patient's dynamic assessment rather than a simple static assessment. The system was retroactively tested with 1250 Medical Reports established by pulmologists, out of which 728 were diagnosed with asthma and 522 were healthy subjects. Sensitivity and specificity were assessed, on this dataset, which were 91.89% and 95.01%, respectively.

In respect with growing population, chronical disease management and aging population, the medicine and health care have drastically changed over the past decades. Engineering became more involved in medicine resulting in development of new discipline, Biomedical Engineering. As new engineering solution for problems in medicine regarding therapy, diagnosis and treatment have emerged, the need for new interdisciplinary educational curriculums evolved. Today, South East Countries are focused on developing new educational curriculums in Biomedical Engineering, following the models established in other European and United States Countries, and recognizing the new discipline - Biomedical Engineering as a professional discipline. International Federation for Medical and Biological Engineering, supported by United Nations (UN), gives support for national societies that are focused on Biomedical Engineering. In this article, overview of development and perspectives of Biomedical Engineering in South East European (SEE) countries is given, with focus on Bosnia and Herzegovina.

This chapter presents a system for classification of chronic obstructive pulmonary disease (COPD) based on fuzzy rules and a trained neural network. Fuzzy rules and neural network parameters are defined according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines. For neural network training more than one thousand medical reports obtained from database of the company CareFusion were used. The system was subsequently validated in 285 patients by physicians at the Clinical Centre University of Sarajevo. Out of the investigated patients, 99.19% of the 248 with COPD and all of the 37 individuals with normal lung function were classified correctly. Obtained sensitivity (99.3%) and specificity (100%) in COPD were assessed, as well. Implemented neuro-fuzzy system for classification of COPD is based on a combination of spirometry and Impulse Oscillometry System (IOS) test results, which enables more accurate classification of the disease. Additionally, a complete patient’s dynamic assessment can be obtained rather than a mere static assessment through the use of bronchodilatation and bronchoprovocation.

In respect with growing population, health care systems are becoming main priority in social-economy policies. Within the modern health care system, overcoming challenges in human health protection, disease prevention, treatment and rehabilitation of patients require engineering involvement. Investment in biomedical engineering (BME) creates a base for progress in many fields, from cutting health care expenses, better quality and accuracy in diagnosis and patient treatment, increase of medical therapies reliability and, finally, improved populations’ life quality. Economic growth, improvement and competitiveness of the country through BME require highly educated engineers, appropriate legislative in accordance with World Health Organization (WHO) and government support. Main goal of this article is to present the basic strategic framework necessary for BME development in Bosnia and Herzegovina, with potential to influence economic growth. This cause-a-consequent connection between economic growth and BME is still unexplored in Bosnia and Herzegovina. Discussing the BME phenomena in Bosnia and Herzegovina has a great significance since it can determine the possible reason for increase in its internal and external funding. The future holds so far unexplored possibilities in the field of BME in Bosnia and Herzegovina, which can lead to social and economic progress, and the first step toward it is to create a strategic framework as a foundation.

In addition to knowledge and experience of medical doctors, correct diagnosis and appropriate patient treatment largely depend on accuracy and functionality of medical devices. In a large number of serious medical situations proper functionality of medical devices is crucial for patients. Therefore it is necessary to carry out as strict and independent testing of functionalities of medical devices as possible and to obtain the most accurate and reliable diagnosis and patient treatment. This paper presents the results of study conducted by the Institute of Metrology of Bosnia and Herzegovina (IMBIH) that highlight the necessity of introducing metrology into medicine and defining standard regulations for inspections of medical devices. As it has been previously done for other kinds of devices that are under jurisdiction of the Institute of Metrology of BH, this research provides a foundation for the introduction of medical devices into the legal metrology system with precisely defined units of measurement, their ranges and errors. The study was based upon data collected through three clinical centers, 25 hospitals, 63 health centers and 320 private health institutions in BH over the course of one year. As a result of this study, the medical devices that have been introduced into the legal metrology system in BH include ECG devices, defibrillators, patient monitors, respirators, anesthesia machines, dialysis machines, pediatric and neonatal incubators, therapeutic ultrasounds, infusion pumps and perfusors. Furthermore, standard inspection regulations for the aforementioned medical devices are also defined. Additionally, a national laboratory for the inspection of medical devices was established and it currently operates under the ISO 17020 standard. With the introduction of medical devices into the legal metrology system and with the establishment of a fully operational national laboratory for inspection of medical devices, we expect that the reliability of medical devices in diagnosis and patient care will increase and that the costs of the health care system in BH will be reduced.
