Given the growing number of older people, society as a whole should ideally provide a higher quality of life (QoL) for its ageing citizens through the concept of personalised ageing. Information and communication technologies (ICT) are subject to constant and rapid development, and can contribute to the goal of an improved QoL for older adults. In order to utilise future ICT solutions as a part of an age-friendly smart environment that helps achieve personalised ageing with an increased QoL, one must first determine whether the existing ICT solutions are satisfying the needs of older people. In order to accomplish that, this study contributes in three ways. First, it proposes a framework for the QoL of older adults, in order to provide a systematic review of the state-of-the-art literature and patents in this field. The second contribution is the finding that selected ICT solutions covered by articles and patents are intended for older adults and are validated by them. The third contribution of the study are the six recommendations that are derived from the review of the literature and the patents which would help move the agenda concerning the QoL of older people and personalised ageing with the use of ICT solutions forward.

Abstract Background The ventricular stroke work (SW) refers to the work done by the left ventricle to eject the volume of blood during one cardiac cycle. The cath-lab relationship between SW and end-diastolic volume (EDV) is the preload-recruitable SW (PRSW). Recently a non-invasive single-beat PRSW (SBPRSW) has been proposed. However, the single beat formula needs mathematical skillness, and extra software. Aim of this study was to compare the non-invasive SBPRSW with the simpler non-invasive SW/EDVratio in the stress-echo lab. Methods We studied 692 patients, age 62 ± 12 years, ejection fraction 50 ± 17%, with negative stress echo (SE)(exercise, n = 130, dobutamine, n = 124, dipyridamole, n = 438) and follow-up data. The PRSW was estimated at rest and at peak stress by the SBPRSW technique and compared with the SW/EDV. All patients were followed-up. Event rates were estimated with Kaplan–Meier curves. Results SBPRSW and SW/EDV were linearly correlated at rest (r = 0.842, p < .001) and at peak stress (r = 0.860, p < .001). During a median follow-up of 20 months (first quartile 8, third quartile 40 months), 132 major events were registered: at receiver operating characteristic (ROC) analysis rest SBPRSW vs. SW/EDV (AUC 0.691 vs. 0.722) and peak stress (AUC 0.744 vs. 0.800) demonstrated both a significant prognostic power (all p < .001) with non-inferior survival prediction of the simpler SW/EDV ratio at Kaplan–Meier curves (Chi-square rest = 38, peak = 56) vs. SBPRSW (Chi-square rest = 14, peak = 42). Conclusions The data obtained with the non-invasive SBPRSW and by the simpler SW/EDV are highly comparable. PRSW with either SB or SW/EDV approach is effective in predicting follow-up events.

Analysis of 4G/5G polymorphisms of PAI-1 gene in interaction with other genetic and external risk factors that induce development of venous thromboembolism can be used for risk assessment for development of venous thromboembolism. Research was conducted on 202 examinees of both genders, older than 18, from north-eastern Bosnia. Experimental group included 100 examinees with diagnosed DVT and 101 examinees who until the sampling procedure did not have diagnosed DVT. In DVT group, following genotype frequencies were determined: 27% of examinees had a normal genotype 5G/5G, 68% are heterozygotes and 5% are mutated homozygotes 4G/4G. In the control group, frequencies of 4G/5G polymorphisms of PAI-1 gene were: 42.6% of examinees have 5G/5G genotype, 55.4% are heterozygotes 4G/5G and 2% are 4G/4G genotype. Obtained results support the hypothesis that PAI-1 in interaction with other genetic and external risk factors probably induces the development of venous thromboembolism.

The focus of this article is on the biography and medical activity of Gisela Januszewska (née Rosenfeld) in Austro-Hungarian (AH) occupied Bosnia and Herzegovina (BH) between 1899 and 1912. Rosenfeld, later Januszewska and then Kuhn(ová) by marriage, was the fifth of a total of nine official female physicians who were employed by the AH administration to improve the health and hygienic conditions among Bosnian and Bosnian Muslim women. In 1893, Gisela Kuhn moved from Brno, Moravia to Switzerland to pursue her medical studies; she was awarded her Doctorate in Medicine (MD) from the University of Zurich in 1898. In the same year, she took up her first position as a local health insurance doctor for women and children in Remscheid but was prohibited from practising in the German Empire. In 1899, she successfully applied to the AH authorities for the newly established position of a female health officer in Banjaluka and began working there in July 1899. She lost her civil service status upon marrying her colleague, Dr Wladislaw Januszewski, in 1900 but carried out her previously officially assigned tasks as a private physician. In 1903, she was employed as a 'woman doctor for women' at the newly established municipal outpatient clinic in Banjaluka. Upon her husband's retirement in 1912, the couple left BH and settled in Graz, Styria. After, World War I Januszewska ran a general medical practice in Graz until 1935 and worked as a health insurance-gynaecologist until 1933. She received several AH and Austrian awards and medals for her merits as a physician and a volunteer for humanitarian organisations. Upon Austria's annexation to Nazi Germany 1938, however, she was classified a Jew and was deported to Theresienstadt concentration camp (Terezín, Bohemia), where she died in 1943. CONCLUSION: Gisela Januszewska, née Rosenfeld (1867-1943) viewed her medical practice as a social medicine mission which she put into practice as a 'woman doctor for woman' in Banjaluka, BH (1899-1912) and Graz, Austria (1919-1935).

This article aims to improve spectrum efficiency (SE) for the unmanned aerial vehicle (UAV)-relayed cellular uplinks, through distinguishing both line-of-sight (LoS) and non-LoS (NLoS) links. Meanwhile, aiming to accommodate the air-to-ground (A2G) cooperative nonorthogonal multiple access (NOMA)-based cellular users (CUs) with a high energy efficiency (EE), a joint resource allocation (RA) problem is further considered for the UAV and the CUs. To solve the problem, first, an access-priority-based receiver determination (RD) method is derived. According to the RD result, the heuristic user association (UA) strategies are given. Then, based on the UA result, transmission powers of the CUs and the UAV are initialized based on their quality-of-service (QoS) demands. Furthermore, the subchannels are assigned to the associated CUs and the UAV with the reweighted message-passing algorithm. Finally, the transmission power of the CUs and the UAV is jointly fine-tuned with the proposed access control schemes. Compared with the traditional orthogonal frequency-division multiple access (OFDMA) scheme and the traditional ground-to-ground (G2G) NOMA scheme, simulation results confirm that the UAV-aided NOMA with the proposed joint RA scheme yields better performances in terms of the SE, the EE, and the access ratio of the CUs.

Proportional–integral–derivative (PID) control is the most common control approach used to control active magnetic bearings system, especially in the case of supporting rigid rotors. In the case of flexible rotor support, the most common control is again PID control in combination with notch filters. Other control approaches, known as modern control theory, are still in development process and cannot be commonly found in real life industrial application. Right now, they are mostly used in research applications. In comparison to PID control, PI-D control implies that derivate element is in feedback loop instead in main branch of the system. In this paper, performances of flexible rotor/active magnetic bearing system were investigated in the case of PID and PI-D control, both in combination with notch filters. The performances of the system were analysed using an analysis in time domain by observing system response to step input and in frequency domain by observing a frequency response of sensitivity function.

Introduction: There are several evaluation schemes for the results of tendon transfers in case of radial nerve paralysis, and the most logical and commonly used are evaluation schemes that use the range of active joint movements to evaluate the results. Aim: Present an original evaluation scheme for tendon transfer results based on functional wrist and fingers joint movements. The aim of the article is to present the advantages of our own Functional scheme in comparison with other schemes, its simplicity and applicability in the evaluation of all clinical cases of different postoperative outcome of the variables being evaluated, and to present the ease of comparison of the achieved results with other authors who would possibly use our scheme because it minimizes the subjective error of the examiner. The secondary aim is to compare the results of flexor carpi radialis (FCR) vs. flexor carpi ulnaris (FCU) tendon transfers (TT). Methods: The study was conducted as clinical and retrospective. The study included 60 patients with isolated radial nerve palsy operated by two tendon transfer surgical methods (FCR and FCU) over a 10-year period. The evaluation of the results was performed by using Zachary, Neimann-Pertecke, Tajima evaluation schemes, our own Functional Evaluation Scheme as well as subjective patient evaluation. Results: The time elapsed from injury to surgery ranged from 105 to 956 days in case of FCR tendon transfer and from 109 to 712 days in cases of FCU tendon transfer. The overall average age of patients is 36.71 years. A statistically significant difference in values with t -test based on the Functional Evaluation Scheme was found in the variables of ulnar deviation (p=0.000731), extension of the MP fingers joints II-V (p=0.04610) and extension of the MP of the thumb joint (p=0.0475). Evaluation of the total results with t-test (p=0.007532) and with U-test (p=0,00433) showed statistically better FCR tendon transfer results. A statistically significant difference in value measured by the t-test was found in the evaluation of the overall results (p=0.022) with Zachary and Neumann-Pertecke schemes and by the Tajima evaluation Scheme (p=0.042) in favor of better FCR tendon transfer results. With a use of Functional Evaluation Scheme, it is possible to evaluate all the results unlike most available schemes. Conclusion: The functional evaluation scheme is based on the functional joint movements evaluated and incorporating radial and ulnar deviation of the wrist (RD and UD), extension of the metacarpophalangeal (MCP) joint and flexion of the intephalangeal (IP)joint of the thumb in the final evaluation becomes completely original. A functional evaluation scheme is simply applicable for the evaluation of all clinical cases of different postoperative outcome of the variables being evaluated. FCR tendon transfer achieves better results than FCU TT.

Introduction: Widespread opinion that penetrating chest injuries are more urgent, in terms of treatment and care, contributed to underestimation of the urgency of blunt chest trauma, which in most cases is treated conservatively. It remains an open question frequency when the injuries of the heart and pericardium are not timely diagnosed and surgically treated. Aim: To demonstrate the importance of well-timed surgical treatment of blunt chest trauma, when coupled with cardiac and pericardial injuries. Methods: At the Thoracic Surgery Clinic of the University Clinical Centre Banja Luka, Bosnia and Herzego vina, during period of 10 years (01.01. 2008 – 31.01.2018.), the total of 66 patients were treated for urgent thoracotomy due to clinically and radiologically unclear findings after blunt chest trauma. In general, diagnostic examinations, apart from laboratory analysis, included radiological imaging and Multi Slice Computed Tomography (MSCT) of the chest, followed by an ultrasound of the heart in cases when sternum was injured or when pericardial tamponade was suspected. Results presented in the study where obtained from the retrospective analysis of patients data. This work presents a retrospective observational cross-sectional study, which results in the assessment of the correctness of a particular diagnostic test. Statistical methods used: descriptive statistics, counting measures (frequencies and percentages), central tendency measures (arithmetic mean), variability measures (standard deviation). Results: Sixty six patients were treated with urgent thoracotomy after a blunt trauma of the chest due to the unclear clinical and radiological finding. In the case of 11 patients (10 men and 1 woman), presenting 16.6% of the total sample, pericardial and cardiac injuries were detected and treated intraoperatively. Further, in the case of the one patient, pericardiotomy and suturing of the right heart chamber where performed, with the creation of a pericardial window. Transthoracic echocardiogram was not used as the primary screening module, but rather as a diagnostic test for patients who had unexplained hypotension and arrhythmia. Radiographs of the chest showed cardiomegaly with or without epicardial fat pad sign suggesting a pericardial effusion. Conclusion: Blunt cardiac and pericardial injuries represent a serious therapeutic problem, which, if not treated properly, result in a high mortality rate. Echocardiography is the primary diagnostic method for initial detection of pericardial effusion. Pericardial fluid first accumulates posterior to the heart, when the patient is examined in the supine position. As the effusion increases, it extends laterally and with large effusions the echo-free space expands to surround the entire heart. The size of the effusion may be graded as small ( echo free spaces in diastole <10 mm, corresponding to approxymately 300 ml), moderate (10-20 mm, corresponding to 500 ml), and large ( >20 mm, corresponding to >700 ml). When the ability of the pericardium to stretch is exceeded by rapid or massive accumulation of fluid, any additional fluid causes the pressure with the pericardial sac. Early recognition, pericardiotomy with pericardial window creation and/or ventricular rupture suture remain the “gold standard” in the treatment of blunt cardiac and pericardial injuries.

OBJECTIVE To evaluate and compare the solubility of three luting cements in three different solutions: distilled water and artificial saliva with different pH values (7.4 and 3.0). MATERIALS AND METHODS Resin-modified glass-ionomer cement (GC Fuji Plus) and two resin cements (Multilink Automix and Variolink II) were used. A total of 45 specimens, 15 specimens (15x1 mm) for each cement, were prepared according to ISO standard 4049:2009. The solubility of the cements was calculated by weighing the specimens before and after immersion and desiccation. Values of solubility in water (Wsl) in microgram/mm3 for each of the five specimens were calculated using the following formula (ISO 4049:2009): Wsl=(m1-m3)/V. The Mann-Whitney U nonparametric statistical method and Post hoc sample comparisons were applied. RESULTS GC Fuji Plus showed statistically significant higher solubility in comparison with Variolink II and Multilink Automix in all three solutions. In acidic artificial saliva (pH 3.0) Multilink Automix showed significantly higher values of solubility compared to Variolink II (P<0.016). By studying the effect of pH value on the solubility of GC Fuji Plus cement, significantly higher values of solubility in pH 3.0 artificial saliva were confirmed (P<0.009). The influence of the surrounding pH value on the solubility of the resin cements Multilink Automix and Variolink II was researched. No statistically significant difference was found. CONCLUSION Solubility values were mainly influenced by the proportion of hydrophilic matrix, the type and composition of filler, and the pH value of the solutions.
