Aim To assess hand function and explore the relationship between hand function and neuroimaging findings in children with unilateral spastic cerebral palsy (US CP). Methods Hand function was assessed using Manual Ability Classification System (MACS, I-V). Brain lesions were divided into five groups: brain maldevelopment (MAL), periventricular white matter lesions (PV WM), cortical/subcortical gray matter lesions (C/SC GM), nonspecific and normal findings. Results Of 114 children with US CP (77 boys and 37 girls), 56 were with right-sided and 58 with left-sided involvement. MACS I was found in 49 (42.9%), MACS II in 19 (16.7%), MACS III in 19 (16.7 %), MACS IV in 9 (7.9%) and MACS V in 18 (15.8%) children (p=0.002). Computed tomography (CT) as the only neuroimaging has been done in 18 (15.8%), magnetic resonance imaging (MRI) at 94 (82.5%) children, whereas 2 (1.7%) children had neither CT nor MRI. The CT showed PV WM in eight (44.4%), C/SC GM lesions in 6 (33.3%), and normal findings in 4 (22.2%) children (p=0.709). The MRI showed MAL in 8 ( 8.5%), PV WM in 46 (48.9%), C/SC GM in 28 (29.8%), miscellaneous in 2 (2.1%), and normal finding in 10 (10.7%) children (p=0.0001). Mild hand dysfunction (MACS I and II) was assessed in 68 (59.7%) children, of which 33 had PV WM lesions (p=0.001). Conclusion Mild hand dysfunction in children with US CP has been significantly associated with PV WM lesions. The type of brain lesion may help to identify its timing and predict the level of hand dysfunction.

Introduction: By development of the medicine, control of the risk factors for acute myocardial infarction (AMI), became the foundation of cardiology. Aim: To investigate the association of the age with presence of risk factors in patients with acute myocardial infarction. Methods: The study had a prospective, comparative and descriptive character, and it was done on a sample of 80 patients (n=80; 55 male and 25 female) Clinic for Heart, Blood Vessel and Rheumatic Diseases, Clinical Center University of Sarajevo from January 2016 to August 2018. All patients were hospitalized under the diagnosis of myocardial infarction and were divided into two main groups, which were divided into two subgroups according to age. Group A, group of patients under 45 years of age at the moment of diagnosis of AMI (n = 40; men = 29; women = 11) was divided into group A1 (n = 20; patients aged 25-35 years) and group A2 (n = 20; patients aged between 35-45 years). Group B, patients older than 45 years at the time of diagnosis of AMI (n = 40; men = 26, women = 14) was divided into group B1 (n = 20; patients aged between 45-55 years) and group B2 (n = 20; patients aged 55-65 years of age). Results: According to gender distribution, there is a significantly higher incidence of hypertension in male patients aged 25-35 years and between 35-45 years (p = 0.01; p = 0.01). Increased cholesterol values were significantly more common in men aged 25-35 years (p = 0.0121). Increased triglyceride values were significantly more common in men aged 25-35 years, in comparison to female respondents of the same age (86.67% vs. 13.33%, p = 0.0001). There was a significant significance between the two groups in the occurrence of anteroseptal (p = 0.04) and in the diaphragmatic myocardial infarction (p = 0.01), while in other infarction localities no significant significance was observed. Conclusion: Male sex is a predisposing risk factor for the development of a cardiovascular incident in the younger age. The post infarction ejection fraction of the left ventricle was significantly reduced in younger patients. The potential for prevention should be of paramount importance. The localization of the incident itself, and the involvement of a certain blood, represents, regardless of all the research, still a fact that is hard to stratify and directly correlated with a certain risk factor.

Aim To explore the experience of anaesthetist nurses in brief meetings with immigrant patients in the perioperative setting. Methods The study was conducted through open individualised interviews using open-ended questions. Eighteen anaesthetist nurses (six men and twelve women) participated in the interviews. Their age varied between 35 and 65 and they had worked as anaesthetist nurses for a period between six and twenty eight years. The text was analysed using qualitative content analysis. Results Meetings with immigrant patients made nurses with less experience to prepare more, to study behaviour of these patients and to ask their older colleagues for advice. More experienced nurses acted on the basis of their previous experience and treated the patients in the same way as before. They also emphasised the great responsibility and wider scope of assistance needed by these patients than those born in Sweden. The majority of nurses begin the meetings with these patients by requesting an interpreter, while some nurses begin the meeting directly with the patient and, if they see it is not going well, they request an interpreter. Conclusion Nurses need better guidelines and education in how to deal with the legislation relating to immigrant patients in order to handle the situation more effectively. Training in cross-cultural care should be improved to help nurses deal with stress through co-operation with the Migration Board and others. In order to provide for good communication and patient safety professional interpreters should be used.

Aim To investigate existence of scientific support for linking differences in the experience of pain to ethnicity. Methods The study was designed as a systematic literature review of qualitative and quantitative studies. The inclusion criteria were scientific studies published in scientific journals and written in English. Studies that described children's experiences and animals were excluded. There were 10 studies, one qualitative and nine quantitative. Results The result was divided into two main sections. The first section presents the results of investigated material regarding different ethnic groups, the groups' different experiences with regard to pain and its treatment focusing entirely on the patients' perspective. Several studies have revealed major differences in the way individuals perceive their pain, using various pain evaluation tools. The second section explained different coping strategies depending on ethnicity and showed that different ethnic groups handle their pain in different ways. Conclusion Healthcare professionals have a duty to pay attention to and understand the patients' experience of their disease and suffering and, as far as possible, mitigate this using appropriate measures. For this purpose, ethnic, cultural and religious differences between different patients need to be understood. It is necessary to continue to study ethnic differences in reporting and predicting pain and its consequences, including the assessment of variables associated with pain, as well as examining the use of prayer as a form of dealing with pain, with an evaluation of various effects of such different influences.

This paper aims to analyze the beta convergence of Western Balkan countries towards the EU-15 Member States in the period 2004-2016, and two sub-periods: 2004-2008 and 2009-2013. Beta convergence is based on the neoclassical growth theory and tests the hypothesis that poor countries tend to grow faster than rich countries, in per capita terms. The empirical findings support the economic convergence hypothesis, with convergence rates ranging from 1.1% to 2.3%. The results show that the recent financial crisis negatively affected the absolute and conditional convergence process, when economic variables are included. The main limitation of the research is the availability of data.

Aim To determine dietary habits of elementary school students in relation to a place of living and socio-economic status of the family. Methods A prospective study conducted in the Primary Health Center Zenica involved five family medicine teams in urban and five in rural settlement during 2015. Elementary school students aged 10-16 were interviewed by random selection using a questionnaire on the socio-economic status of parents and nutritional habits of adolescents. Results The survey involved 199 respondents, 103 from rural and 96 from urban area. There were significantly more pupils from employed parents who consumed non-carbonated drinks. Students from urban areas more likely consumed fruit every day than children from rural areas. More than half of the respondents did not or rarely consumed vegetables, in this case the village pupils, who consumed much less milk. It would be expected that rural students were more likely to consume fruits, vegetables and milk due to easier access to these foods in the countryside, but the results of this research did not confirm this assumption. Conclusion Changes in traditional family functioning (lower income, unemployment) could be linked with lifestyle changes (low consumption of fruits and vegetables, low consumption of milk both in rural and urban areas, consumption of carbonated drinks), especially in families in rural areas.

Aim To develop an online biofilm calculation tool (Biofilm Classifier), which calculates the optical density cut off value and accordingly determines the biofilm forming categories for the tested isolates by standardized formulas, as well as to compare the results obtained by Biofilm Classifier to manual calculations and the use of predefined values. Methods The biofilm forming capacity of tested strains was evaluated using tissue culture plate method in 96 well plates, and optical density (OD) value of the formed biofilm was measured on an ELISA Microplate reader at 595 nm on a total of 551 bacterial isolates from clinical specimen. Results Comparative analysis indicated that the manual calculation was 100% in accordance with results obtained by the designed software as opposed to the results obtained by use of predefined values for biofilm categorization. When using predefined values compared to manual biofilm categorization for the determination of biofilm positive and biofilm negative strains the specificity was 100%, sensitivity 97.81%, positive predictive value 100%, negative predictive value 96.04% and accuracy 98.57%. Conclusion Considering obtained results, the use of the designed online calculator would simplify the interpretation of biofilm forming capacity of bacteria using tissue culture plate method.

Aim To present our experience with a diagnostic ability of endoscopic ultrasound (EUS) and magnetic retrograde cholangiopancreatography (MRCP) in cases of choledocholithiasis verified by endoscopic retrograde cholangiopancreatography (ERCP). Methods This retrospective study was conducted after a collection of data involving 58 suspected choledocholithiasis patients who underwent ERCP from January 2013 to December 2015. Patients who were diagnosed with choledocholithiasis on the basis of clinical symptoms and radiological findings and who underwent ERCP were included in this study. The first group (29 patients) underwent EUS, and the second group (29 patients) underwent MRCP. The ERCP was performed in both groups. Sensitivity, specificity and diagnostic accuracy of EUS and MRCP were determined by comparing them with ERCP, which was considered to be a gold standard. Results Gender representation was in favour of males, 58:42%. The mean age was 55.5 years. In the group 1 (EUS) 22 patients were found to have choledocholithiasis using ERCP. The EUS stone detection rate was 88%. Endoscopic ultrasound showed sensitivity (97%), specificity (67%) and accuracy (88%), positive predictive value (PPV) of 88%, negative predictive value (NPV) of 80%. In the group 2 (MRCP) 16 patients were found to have choledocholithiasis by ERCP. MRCP sensitivity was 81%, specificity 40%, PPV of 74%, NPV of 50%. Conclusion The EUS was a superior non-invasive tool in comparison with MRCP for detecting choledocholithiasis, which was confirmed using ERCP.

Aim To investigate etiological link between acute myocardial infarction (AMI) and the accompanying impotence/erectile dysfunction (ED). Methods Study included 99 male patients (48 who had AMI - patient group, and 51 healthy examinees without previous cardiovascular disease - control group). All patients completed a standardized questionnaire, the International Index of Erectile Function (IIEF-5). Results Older patients had significantly lower IIEF-5 score (negative correlation) (p<0.05), but higher ED degree (significant positive correlation) (rho=0.522; p=0.0001). In the patient group, 37 (77.1%) patients had ED, while in the control group it was found in 26 (51%) examinees (p<0.05). A clear correlation was found between incidence of ED and diabetes, dyslipidaemia, hypertension and positive family history (they were more common in patients with ED, with no statistically significant difference). There was no statistically significant difference between patients with ED and patients without ED according to the beta-blocker usage (p=0.824): ED was reported in 11 (68%) patients in the group who used carvedilol, 14 (82.3%) in the group who used metoprolol, and nine (81.8%) who used nebivolol. Conclusion Myocardial infarction as well as age are directly related to the occurrence of ED. Cardiovascular risk factors are in direct correlation for the occurrence of erectile dysfunction after myocardial infarction.

Aim To investigate the prevalence and obstetrical characteristics of low birth weight infants (LBWIs) in ten Cantons of the Federation of Bosnia and Herzegovina (FBiH). Methods The prospective study included newborns of both genders, gestational age (GA) of 22 to 42 weeks and birth weight(BW) of less than 2,500 grams in the period 1 January 2009 to 31 December 2009. Results In the observed period, 22897 neonates were born, out of whom 669 (2.9%) had a BW less than 2500 grams (average BW was 1295 grams; SD ± 234.2; a coefficient of variation of 0.58). The average GA was 31.4 weeks of gestation. The average lifespan of mothers was 27.7 years (SD ± 1.2). The average Apgar scor (AS) in the first minute was 4.6 (SD ± 2.1) and in the fifth minute it was 6.6 (SD ± 1.9). The LBWIs were most commonly delivered by primiparas, 317 (47.5%). Of the 669 LBWIs, 411 (61.4%) were born per vias naturalis, with cephalic presentation. The highest number of LBWIs was born in Sarajevo Canton, 3.7%, and Central Bosnia Canton, 3.7%. The lowest prevalence was in Posavina Canton, 1.1%. The largest late fetal mortality was in Central Bosnia Canton, 7.7 ‰. Conclusion This study has determined a relatively low prevalence of LBWIs and other examined obstetrical characteristics that are in correlation with European and Global World data.

Introduction The exact mechanisms of periapical bone resorption have not been fully elucidated. This study aimed to analyze the expression of Notch signaling molecules (Notch2, Jagged1, and Hey1) and proinflammatory cytokines (tumor necrosis factor alpha [TNF‐&agr;], interleukin [IL]‐1&bgr;, and IL‐6) in human apical periodontitis lesions with different receptor activator of nuclear factor kappa B ligand (RANKL)/osteoprotegerin (OPG) ratios and determine their potential correlation. Methods The study group consisted of 50 periapical lesions collected in conjunction with apicoectomy. The relative gene expression of the investigated molecules (Notch2, Jagged1, Hey1, RANKL, OPG, TNF‐&agr;, IL‐1&bgr;, and IL‐6) in all tissue samples was analyzed using reverse transcriptase real‐time polymerase chain reaction. The Student t test, Mann‐Whitney U test, and Spearman correlation were used for statistical analysis. Results Based on the RANKL/OPG ratio, periapical lesions were either RANKL predominant (RANKL > OPG, n = 33) or OPG predominant (RANKL < OPG, n = 17). Symptomatic lesions occurred more frequently in RANKL‐predominant compared with OPG‐predominant lesions (24 vs 7, P = .029). Notch2, Jagged1, Hey1, and TNF‐&agr; were significantly overexpressed in lesions with predominant RANKL compared with lesions with predominant OPG (P = .001, P = .001, P = .027, and P = .016, respectively). Significant correlations were observed between the investigated genes in periapical lesions. Conclusions Notch signaling appeared to be activated in periapical inflammation. An increase in Notch2, Jagged1, Hey1, and TNF‐&agr; expression in RANKL‐predominant periapical lesions corroborates their joined involvement in extensive periapical bone resorption.

Abstract In this video, we demonstrate epidermoid tumor microsurgical resection of the cerebellopontine angle (CPA) performed by the senior author (K.I.A.). Epidermoid tumors arise from ectoderm trapped within/displaced into the central nervous system. They show predilection for CPA Angle (up to 40%), 4th ventricle, suprasellar region, and spinal cord.1 They are the 3rd most common CPA tumor, comprising approximately 7% of CPA pathology. CPA lesions can produce 5th and 7–12th cranial nerve neuropathies.2 3 4 Recurrent episodes of aseptic meningitis caused by cyst content rupture may occur. Symptoms include fever, meningeal irritation, and hydrocephalus. A 26-year-old female presented with headaches. Head magnetic resonance imaging (MRI) revealed right CPA tumor with brain stem compression (Fig. 1, A–C). There was evidence of restricted diffusion in diffusion-weighted imaging, typical of epidermoid tumor. Surgery was performed in prone position with head turned 25 degrees to the ipsilateral side using retrosigmoid craniotomy.5 Tumor was ventral to the 7th and 8th cranial nerve complexes, between the 5th nerve as well as toward the brainstem. The surgical plan was gross total resection with tumor capsule resection to prevent recurrence.6 (Small residuals can be left behind when capsule is adherent to critical structures.) Tumor was adherent to brain stem perforators which were preserved using meticulous dissection. Cranial nerves and vascular structures were also left intact. We irrigated with antibiotic saline and used perioperative treatment to prevent aseptic meningitis. The pathohistological diagnosis revealed epidermoid tumor cyst. Postoperative MRI revealed complete resection (Fig. 1, D–F). The patient recovered fully and was neurologically intact. The link to the video can be found at: https://youtu.be/LyWl-KZUSGY.

The impact of interfaces and heterojuctions on the electronic and thermoelectric transport properties of materials is discussed herein. Recent progress in understanding electronic transport in heterostructures of 2D materials ranging from graphene to transition metal dichalcogenides, their homojunctions (grain boundaries), lateral heterojunctions (such as graphene/MoS2 lateral interfaces), and vertical van der Waals heterostructures is reviewed. Work on thermopower in 2D heterojunctions, as well as their applications in creating devices such as resonant tunneling diodes (RTDs), is also discussed. Last, the focus turns to work in 3D heterostructures. While transport in 3D heterostructures has been researched for several decades, here recent progress in theory and simulation of quantum effects on transport via the Wigner and non‐equilibrium Green's functions approaches is reviewed. These simulation techniques have been successfully applied toward understanding the impact of heterojunctions on transport properties and thermopower, which finds applications in energy harvesting, and electron resonant tunneling, with applications in RTDs. In conclusion, tremendous progress has been made in both simulation and experiments toward the goal of understanding transport in heterostructures and this progress will soon be parlayed into improved energy converters and quantum nanoelectronic devices.
