Aim To evaluate a correlation of serum level of neutrophil gelatinase-associated lipocalin (NGAL) to the risk of the occurrence of complications in patients with the early phase of ST-segment elevation myocardical infarction (STEMI) treated with fibrinolytic therapy prior to percutaneous coronary intervention (PCI). Methods A total of 54 patients with the diagnosis of STEMI treated with fibrinolytic therapy (alteplase) prior to PCI were included. Patients were admitted to the Intensive Care Unit (ICU) of Clinic for Heart, Blood Vessel and Rheumatic Diseases in the period January to March 2018. All patients underwent coronary angiography and PCI within the maximum of 48 hours delay after fibrinolysis, according to the hemodynamic and electrical stability and PCI availability. Blood samples were taken immediately after admission prior to fibrinolytic administration. Patients were divided into two groups according to NGAL values (less or more than 134.05 ng/mL). Results Higher values of NGAL have effect on a higher mean systolic and diastolic pressure (p=0.001 and p=0.003, respectively). Patients with higher NGAL values also have higher values of brain natriuretic peptide (p=0.0001) and highly sensitive troponin I (p=0.002). In that group relative risk (RR) for lethal outcome was 6.4 times significantly higher (p=0.002), for the development of heart failure 2.88 times (p=0.0002), for post-myocardial infarction angina pectoris 2.24 times (p=0.0158), and for ventricular rhythm disturbances (ventricular tachycardia, ventricular fibrillation) 1.96 times higher (p=0.0108). Conclusion Increased NGAL value is related to an unfavourable outcome of patients in the early phase of STEMI treated with fibrinolytic therapy prior to PCI.

Long QT syndrome (LQTS) is a rare (1:2500–1:10,000) inherited disorder characterized by the onset of arrhythmogenic syncope, polymorphic ventricular tachycardia, and sudden cardiac death. The aim of this article was to describe an unexpected success with an unusual therapeutic modality of a patient diagnosed with LQTS syndrome (suspected Romano–Ward syndrome) during an 8-year period. A 59-year-old female patient was admitted to the hospital due to chest pain and nausea, and after diagnostic and therapeutical approach, a permanent dual-chamber rate-modulated (DDDR) pacemaker was implanted instead of the implantable cardioverter defibrillator (ICD). During the 8-year period, the patient remained stable, without rhythm disorder. Romano–Ward syndrome as a congenital LQTS carries a high risk of sudden cardiac death and presents an indication for ICD. In this patient, for objective reasons, this could not be performed. Implantation of a DDDR with an appropriate pharmacological therapy, including propranolol, in this case, proved to be a successful therapeutic modality.

The aim of the paper was to examine the effect of noise on the blood flow velocity through a period of three years on workers who work on press machine. It was proven that continuous exposure to noise affects the blood flow velocity through the aorta and increases the diameter of ascending aorta and this, consequently, leads to an increase in cardiovascular risk. Prevention of changes in the cardiovascular system is considered to be imperative, and the limitation of noise levels and the length of exposure to noise must be established as factors that must be planned during the construction of the work environment.

Ab s t r Ac t Introduction: Preeclampsia is the cause of increased morbidity in mothers, and mortality and morbidity of both mothers and fetuses and newborns. The pathological process is already complete when the symptoms occur, and nothing concrete can be done to stop the process. Early identification of women at risk of developing preeclampsia is a key goal of antenatal care. Alongside chemical tests, Doppler sonography of the uterine arteries plays a major role in the prediction of preeclampsia. Aims: To establish the probability of resistance to blood flow in the uterine arteries and the existence of notching in the control and test groups. Materials and methods: The study comprised 60 subjects in the second trimester of pregnancy who were going for check-ups during their pregnancy or had been hospitalized at the Maternity Clinic of Sarajevo UCC. All the subjects were divided into two groups, a control and a test group, in relation to the presence of pathological blood flow in the uterine arteries. As well as ultrasound results, the patients also provided an exhaustive history about their previous pregnancies, if any, and any relevant laboratory results. Results: A statistically significant difference was found in the average values of systolic and diastolic pressure during pregnancy between the control and the test group (p = 0.001). From an analysis of the resistance to blood flow in the uterine arteries in the control and test groups, we concluded that the flow on the side with the placenta and on the side without the placenta were physiological over five measurements in the control group of subjects. In the test group the largest number of cases of pathological flow were recorded, and there was also notching. Of the 21 subjects with a diagnosis of preeclampsia, there was notching in 10. Conclusion: Doppler sonography in the second trimester of pregnancy is a good prognostic marker for early discovery of preeclampsia.

Introduction: Preeclampsia is defined as hypertension (systolic pressure ≥140 mmHg or diastolic pressure ≥90 mmHg) after week 20 of gestation with one or more of the following symptoms: proteinuria, organ dysfunction (including renal, hepatologic, hematologic or neurological complications) and in case of stagnation of fetal development. So far, there are no valid clinical tools or tests that can tell with sufficient sensitivity and specificity in early pregnancy which pregnant woman will develop preeclampsia or have unwanted outcomes. Aim: To present the properties of biochemical parameter, uric acid, in patients with signs of preclampsia, which was confirmed by Doppler sonography. Methods: The study included 60 female subjects in the second trimester of pregnancy who were examined or were hospitalized at the Clinic of Gynecology and Obstetrics, Clinical Center University of Sarajevo. Pregnant women who had normal Doppler sonography scan of the uterine arteries in the second trimester of pregnancy were included in the control group, while pregnant women with pathologic Doppler sonographic findings in the second trimester of pregnancy were included in the group of pregnant women at risk of preeclampsia, i.e. the study group. Results: There is statistically significant difference between the average value of uric acid in the control and in the study group (213.36 ± 28.96 μmol / L vs 249.73 ± 47.06 μmol / L) (F = 12.991; p = 0.001). Applying the Wilcoxon non-parametric paired test to the average uric acid values during all measurements within the control group, no statistically significant difference was found. There was a statistically significant increase in the study group between all measurements, from 18.04 μmol / L between the first and second measurement (Z = -1.955; p = 0.043), 29.10 μmol / L between the second and third measurement (Z = -2.973; p = 0.003), 37.27 μmol / L between the third and fourth measurement (Z = -4.325; p = 0.001) and 109.87 μmol / L at the end of the study in comparison to values from the start of the study (Z = -4.309; p = 0.001). Conclusion: Uric acid values should become part of a broad biochemical range in screening and optimizing the treatment of patients diagnosed with early preeclampsia.

The action of forces in the back and abdomen under conditions of loading of different external forces at different bending angles is unexplored area. This paper presents a methodology that enables calculation of the magnitudes of forces in the back and abdominal muscles using the combined techniques of the CATIA software system, appropriate mathematical model and polynomial regression analysis. The person of 180cm in height and 85 kg in weight is loaded with 5 + 5 kg of cargo in both hands, and three cases of bending angles of 150, 300 and 600 relative to the vertical axis are analysed.

Background: The aim of the article was to create an appropriate computer model based on the real status of the mortar operator's workplace and to analyze the workplace. After that, for any possible exceedances from the aspect of the organism's load and safety, the aim is to redesign the workplace and bring it within the limits of the permissible load, and therefore the required safety. The aim is also to identify the characteristic work movements performed by the soldier and to carry out an ergonomic analysis of the soldier's efforts and to propose appropriate improvements. Methods: The analysis is performed on a total of 20 soldiers, from which is determined an average model of the following characteristics: 180 cm in height and 85 kg in weight. The task is to take a mine from the shell containing the mines, then transfer it to the mortar and fill the mortar barrel. The weight of the 120 mm mortar grenade is 14.8 kg. The average soldier is 26 years old and his military exercise lasts 4 hours. The CATIA software package (Dassault Systemes, Velizy-Villacoublay, France) is used for analysis. By knowing the anthropometric and work environment data, with ergonomic design and analysis, the following analyses were made: biomechanical analysis, rapid upper limb assessment (RULA) and carry analysis (option from CATIA software). Results: The proposed modification of the position resulted in a decrease in the L4/L5 torque from 316 Nm to 154 Nm along with decreasing of the compression force on the L4/ L5 from 5779 N to 3038 N (the compression force allowed is 3400 N), and while the RULA analysis is from the red color position 1 (score 7; maximum load requiring rapid repositioning of such position), revised final score 4 made in yellow (a solution acceptable for this work place). Conclusions: By ergonomic analysis, obtained proposal will lead to less chance of injury, prevention of burn out syndrome, fewer chances of illness, decreasing the fatigue, greater safety, less energy spent and better preparedness for all necessary tasks.

Aim To examine the effects of therapeutic hypothermia on the outcome of patients with the diagnosis of out-of-hospital cardiac arrest (OHCA). Methods The study included 76 patients who were hospitalised at the Medical Intensive Care Unit (MICU) of the Clinical Centre University of Sarajevo, with the diagnosis of out-of-hospital cardiac arrest, following the return of spontaneous circulation. Therapeutic hypothermia was performed with an average temperature of 33oC (32.3 - 34.1o C) on the patients who had coma, according to the Glasgow Coma Scale (GCS). Results Multiple organ dysfunction syndrome (MODS) significantly affected survival (p=0.0001), as its presence reduced patients' survival by 96%. In addition, ventricular fibrillation (VF) as the presenting rhythm, also significantly affected survival (p=0.019). A degree of patient's coma, as measured by the GCS, significantly affected survival (p=0.011). For each increasing point on the GCS, the chance for survival increased twice. Moreover, other physiological factors such as the pH and the lactate serum levels significantly affected patients' survival (p=0.012 and p=0.01, respectively). Conclusion In patients with the diagnosis of OHCA who underwent to the treatment with therapeutic hypothermia, verified VF as a presenting rhythm was a positive predictive factor for their outcome. Therefore, therapeutic hypothermia represents an option of therapeutic modality for this type of patients.
