Authors: Câmara Paulo E.A.S. , van Rooy Jacques , Silva Micheline Carvalho , Magill Robert E. 
Published: July 2019

Abstract
In the Flora of southern Africa area, comprising the countries of South Africa, Namibia, Botswana, Lesotho and Swaziland, the moss family Sematophyllaceae consists of three genera (Trichosteleum, Donnellia and Sematophyllum) and nine species. Core sematophyllous taxa with collenchymatous exothecial cells, long rostrate operculum, linear leaf cells and differentiated alar cells are included in the family. Meiothecium fuscescens is transferred to Donnellia and a new combination made. Sematophyllum wageri is reduced to synonymy under S. brachycarpum and a lectotype is designated for S. dregei. Each species is described and its distribution mapped.

Published: July 2019

Abstract
Background: : Health-related quality of life (HRQoL) is a parameter that is examined in the area of clinical effectiveness. Like other chronic health conditions, paediatric cystic fibrosis (CF) impacts not only children but also their families.
Aim: The present study investigates for the first time the HRQoL of children and parents in the Republic of North Macedonia.
Materials and methods: The survey included 22 children (6 to 13 years of age) and their parents and 7 parents of children under 6 years of age by using the CFQ Revised and questions for current medical treatment.
Results: Children (6-13 years) reported the highest score for the digestive condition (84.85), while the lowest score was given for social activity (59.74). The highest score for digestive condition was also obtained from the parents of children from 6-13 years and under age of 6. The parents of children (6-13 years) reported the lowest score (60.56) for treatment burden activity, while the lowest score (50.0) for eating condition was obtained from the parents of children under 6 years.
Conclusion: Nationality and gender have no significant impact on the HRQoL parameters. The highest scores for the digestive condition, respiratory function and physical condition are in a positive correlation with the fact that enzyme, antibiotic and physical therapy are given as a standard medical care. The lowest scores of the social aspect of the CF patients indicate the need for including a psychological support and support of social workers as a part of the standard medical care of these patients.

Published: July 2019

Abstract
Aim: Iron deficiency anemia (IDA) is a common medical condition, yet there is still some diagnostic uncertainty in this respect. The aim of this study was to compare the clinical significance of biomarkers of iron deficiency (ID) in diagnosing IDA and iron-deficient erythropoiesis in anemic patients.
Materials and methods: A total of 103 untreated patients with non-hemolytic anemia were included. Blood count, reticulocyte hemoglobin content (CHr), iron, transferrin saturation (TSAT), ferritin (Ferr), soluble transferrin receptor (sTfR) and sTfR/logFerr index (sTfR-F index) were determined in the patients.
Results: TSAT<16% diagnosed 79 patients with IDA (76.6%), Ferr<30 µg/l - 50 patients with IDA (48.5%). Thomas-plot analysis found 76 patients with ID (73.8%) and 56 of them were with iron-restricted erythropoiesis and IDA (54.4%). Biomarkers of ID were significantly different in anemic patients with iron-deficient erythropoiesis (CHr<28 pg) compared with patients with normal hemoglobinisation (p<0.001). With regard to the predictive value of the parameters of ID for iron-deficient erythropoiesis in anemia, their mutually controlled influence proved sTfR-F index only as independent statistically significant (p=0.011). The optimal cut-off value of sTfR-F index from the ROC curve analysis for detecting iron-deficient erythropoiesis in anemia (CHr<28 pg) was 1.35, with sensitivity of 82.1% and specificity of 80.9% (AUC 0.866; p<0.001).
Conclusions: Diagnosis of IDA depends on the applied biomarkers of ID, and TSAT or ferritin when used alone may lead to diagnostic difficulties. Combining sTfR-F index and CHr to evaluate iron-deficient erythropoiesis in patients with anemia in addition to ferritin and TSAT could contribute to improving the diagnosis of IDA in clinical practice.
Influence of Company Size on Accounting Information for Decision-Making of Management
Authors: Horvat Tatjana , Mojzer Jožica 
Published: July 2019

Abstract
The aim of this paper is to show the importance of accounting information for management, especially in medium-sized companies. Sampling was carried out according to the accidental principle, after which we selected 300 medium-sized and large companies. We used the questionnaire, which was standardized and implemented online. Two hypothesis were tested with a chi-square test and contingency table. In this study of Slovenian large and medium companies, we want to find out whether the size of the company has an impact on organizing a specific controlling service in a company and whether, in large companies, heads of accounting are more often members of management than in mediumsized enterprises. We discovered a bias between organizing a specific controlling department and the size of a company, and that large companies have more often organized a special controlling service than medium-sized enterprises. We also discovered the accounting officer’s membership in a company’s management team is not related to the size of a company. The results of the research could be used in controlling in medium-sized companies, where we suggest that management accounting in these companies is part of management decisions.

Published: July 2019

Abstract
The central aim of the article is company governance, i.e., researching governance of a company that does not want to be only financially successful but also direct its governance toward socially responsible governance. The article begins with the definition of “theoretical backgrounds,” in which social responsibility in regard to company governance improvement in quality is explained. The article then focuses on the measurement of the quality of company governance; in the research, the selected tool chosen to evaluate the governance of the chosen company regarding social responsibility, i.e., SEECGAN index, is used. Further, the case study of a Slovenian public limited liability company is used. One of the important research findings is the recognition that the addressed part of the SEECGAN index needs to be innovated and further developed. Additional questions for the completion of the index used presents the added value of the article. This article has two limitations: 1) it focuses only on the tool chosen to evaluate the governance of the chosen company regarding social responsibility; 2) the case study is based on publicly accessible data.
Developing Theory of Mind Twenty-Five Years After the Publication of “Z Badań Nad Kompetencją Komunikacyjną Dziecka” (Edited by B. Bokus and M.Haman)
Authors: Haman Maciej 
Published: July 2019

Abstract
Twenty-five years ago, a book “Z badań nad kompetencją komunikacyjną dziecka”, edited by Barbara Bokus and Maciej Haman, was issued containing, among else, the first Polish review of the studies on the development of Theory of Mind. During these 25 years, the area developed extensively and a new “state-of-the-arts” paper is necessary. The current paper does not pretend to the role of a complete review, instead it focusses on two live issues in the Theory of Mind (ToM) research progress: early (before the age of four years) competences in false-belief understanding, which leads to the question of continuity versus discontinuity (e.g., “Two-system theory”) between early and later ToM abilities, and neuroimaging studies of Theory-of-Mind, which may also contribute to the continuity debate.

Authors: Kunicka Magdalena , Litwin Wojciech 
Published: July 2019

Abstract
In recent years, there has been a significant development in “green” and energy efficient propulsion systems, which fits into the general trend of environmentally friendly “green shipping”.
The pursued goal is to construct a safe passenger ship that is low in energy demand and equipped with a highly energy efficient, emission-free propulsion system.
The paper presents main problems encountered by designers of a small, hybrid-powered ferry powered lithium batteries. The conducted research allowed to create a design of an energy efficient hull shape, which decreases the demand for energy. Completed remote control model tests resulted in a proposal of an energy efficient and safe propulsion system with good manoeuvring capabilities. Measurements completed on an existing ferry permitted completing energy balance and forming an energy management policy.
The paper contains the emission calculations computed for the existing ferry that are necessary for the environmental impact analysis.
The soon to be constructed, newly designed vessel will provide a valuable contribution to hybrid-propulsion, energy management and unmanned technologies research.

Published: July 2019

Abstract
In the shipbuilding industry, it is difficult to create CAD models of existing or prototype parts, especially with many freeform surfaces. The paper presents the creation of the CAD 3D model of a shipbuilding component with the application of the reverse engineering technology. Based on the data obtained from the digitization process, the component is reconstructed in point cloud processing programs and the CAD model is created. Finally, the accuracy of the digital model is estimated.

Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune disease that causes erosive changes and ankylosis of joints and may cause internal injuries. Osteoarthritis (OA) is a degenerative process of the articular cartilage. However, inflammatory mediators may play a pivotal role in the initiation and perpetuation of the OA process. It is necessary to continue to study possible factors that may promote the development of the disease. The goal of this study was to evaluate the frequency and activity stage of parvovirus B19 (B19V) and persistent human herpes virus (HHV)-6 and HHV-7 infection in RA and OA patients, and healthy persons, in relation to cytokine levels and presence or absence of viral infections. RA patients with active B19V infection had the highest levels of tumour necrosis factor alpha (TNF-α), which may contribute to the development of RA. In the case of OA, the TNF-α level was higher in patients with active persistent B19V infection, suggesting that B19V reactivation affects also OA. Interleukin (IL)-6, IL-10 and metalloproteinase (MMP)-9 levels were higher in RA patients with latent HHV-6/-7 infection in comparison with active HHV-6/-7 infection, whereas in OA patients levels of all studied cytokines were very variable, ranging from low to high but without significant differences. This suggests that also latent HHV-6 and -7 viral infections can promote development of RA.

Published: July 2019

Abstract
The aim of this study was to assess the relationship between HLA Class II alleles in two groups of patients in Latvia: patients with cystic and alveolar echinococcosis. The study included 37 patients from the Rīga East Clinical University Hospital with echinococcosis (29 patients with cystic echinococcosis and eight patients with alveolar echinococcosis) and 100 healthy control persons without echinococcosis. HLA Class II allele genotyping was performed using Real-time polymerase chain reaction–sequence specific primer (RT-PCR-SSP). The odds ratios (OR), with 95% confidence intervals (95% CI), were calculated using statistical analysis performed with IBM SPSS Statistics for Windows, Version 22.0, to evaluate the risk of developing the disease in an individual having a particular HLA genotype. In the case of cystic echinococcosis a more severe course of a disease can be anticipated in the presence of HLA-DRB1 alleles *17:01 and *07:01, -DQB1 *03:02, and *03:01, -DQA1*04:01 and haplotypes HLA-DRB1*04:01/-DQB1*03:01/ -DQA1*03:01, HLADRB1*11:01/ -DQB1*03:01 /-DQA1*05:01. However, in the group with alveolar echinococcosis it was associated with the HLA-DRB1 alleles *17:01 and *07:01, -DQB1 *05:01 and haplotypes HLA- DRB1*17:01/-DQB1*02:01-2/-DQA1*01:01, HLA-DRB1*11:01/ -DQB1*03:01/-DQA1*01:03 and HLA-DRB1*11:01/-DQB1*03:01/-DQA1*03:01. HLADRB1*15:01/-DQÂ1*06:02-8/-DQA1*05:01 and HLA-DRB1*13:01/-DQB1*02:01-2/-DQA1*05:01 haplotypes were protective in all patient groups. The limitations of this exploratory study indicate that a broader study needs to be conducted for revealing specific risk and protective HLA Class II haplotypes for patients with cystic and alveolar echinococcosis in Latvia.

Published: July 2019

Abstract
In developed and developing countries, most cases of acute gastroenteritis in children are caused by viruses, and rotaviruses are known as the leading cause. The aim of our study was to estimate the main circulating serotypes of rotavirus before the introduction of routine immunisation in Latvia, and to search for their possible correlation with clinical symptoms and circulating genotypes. A cross-sectional study was carried out among children who had been hospitalised in the Children’s Clinical University Hospital from April 2013 to December 2015. Genotyping was done for 462 stool samples. Among G/P combinations, the most predominant genotypes were G4P[8] (61.3%), G9P[8] (12.4%) and G2P[4] (10.0%) in children of age < 5 years, G4P[8] (45.5%), G2P[4] (18.2%), G9P[8], G3P[8], and G1P[8] (9.1%) in children of age > 5 years. There was a statistically significant correlation (p < 0.05) between clinical signs (vomiting, dehydration, chronic diseases) and G1P[8] and G8P[8] genotypes. Infants infected with genotype G4P[4] had a statistically significant negative correlation with severity of acute gastroenteritis episodes (p < 0.05). We detected nine different rotavirus G genotypes, and two different P genotypes. G4P[8], G9P[8], and G2P[8] were predominant. We observed correlation between the dominant genotypes and clinical manifestations of rotavirus infection.

Published: July 2019

Abstract
The role of inflammation in the development of osteoarthritic joint degeneration is not completely understood. Recent data suggest that processes that cause and orchestrate inflamed synovial lesions may be implicated in the development of the disease. The morphological changes of the synovium in patients with osteoarthritis (OA), as well as the level of synovial inflammation cautiously graded, in association to the presence of human parvovirus B19 (B19V) infection markers, were evaluated. Qualitative and quantitative detection of B19V genomic sequence was performed in OA and rheumatoid arthritis (RA) groups. The expression of CD68, S100 (Ca2+ binding proteins soluble in 100% ammonium sulfate) and B19 VP1/VP2 capsid proteins found in the synovium were investigated by single and double immunolabeling, whereas fine features of synoviocytes — by electron microscopy. One-third of OA and RA patients demonstrated synovial expression of B19V antigen, which was confirmed in both types of synoviocytes. The overall expression of B19V in OA patients was weaker than that found in RA subjects. Positive correlation between B19V-positive vascular endothelial cells, sublining infiltrating lymphocytes, macrophages, and B19V-positive synoviocytes was established. No correlation between synovitis score indices as well as the expression of S100 and expression of B19V was found. The results suggest that the synovial membrane maintains local joint homeostasis, and that virus mediated synovitis is implicated in the development of OA.

Abstract
The aim of this study was to evaluate the utility of the pathological personality traits in predicting suicidal ideation, especially in combination with other risk factors, such as the level of depression, prior attempts of suicide, low self-esteem, low level of perceived social support and self-esteem-by-social support interaction, both in general and in psychiatric inpatient samples. Data were analysed within two samples: non-clinical general sample (n = 461) and psychiatric inpatient sample (n = 131). Latvian Clinical Personality Inventory (LCPI) was used as the instrument for data collection. LCPI is a comprehensive multi-scale multi-item inventory, which consists of nine clinical scales (including Depression Symptom Scale), 33 pathological personality scales, five functioning scales, and five additional scales, including a Suicidal Ideation Scale, Low Self-esteem Scale and Lack of Perceived Social Support Scale. Results of the hierarchical regression analysis showed that several facet-level pathological personality traits (depressivity, self-harm, dissociation proneness, submissiveness, and suspiciousness) added significant incremental variance to the prediction of suicidal ideation above and beyond the well-known main risk factors of suicidal ideation, such as depression and prior suicide attempt. This effect remained stable even after taking into account additional interpersonal risk factors, such as low self-esteem, low level of perceived social support and self-esteem-by-perceived social support interaction. The incremental effect of personality traits was medium in the psychiatric inpatient sample and small in the general sample. Findings of the study may assist in early screening for persons with suicide risk and for developing prevention programmes in different settings.

Abstract
Variable platelet response to aspirin and clopidogrel is a well-known phenomenon in patients with coronary artery disease and ischemic cerebral stroke. The objective of the present study was to evaluate the frequency and possible risk factors of antiplatelet resistance in patients with cerebrovascular and cardiovascular diseases. The VerifyNow system was used to evaluate adenosine-5-diphosphate and platelet P2YI2 receptor function in patients with cerebrovascular and cardiovascular disease, who received dual antiplatelet therapy. Aspirin resistance was defined as aspirin reaction units (ARU) ≥ 550. Clopidogrel resistance was defined as Platelet Reaction Units (PRU) > 230. In the group of cerebrovascular diseases there were 13.2% (n = 27) patients with aspirin and 24.5% (n = 50) with clopidogrel resistance. However, in the cardiovascular group there were 20% (n = 9) aspirin and 11.1% (n = 5) clopidogrel resistant patients. In the cerebrovascular group, aspirin resistant patients had a lower triglyceride level (p = 0.001, r = 0.26) than aspirin sensitive patients. Clopidogrel resistant patients had a significantly higher level of glycated haemoglobin (HbA1C) (p = 0.016, r = 023), triglycerides (p = 0.033, r = 0.16) and lower level of high-density lipoproteins (p = 0.027, r = 0.16) than clopidogrel sensitive patients. In the cardiovascular group, patients who were resistant to aspirin had a significantly higher high-density lipoprotein level (p = 0.038, r = 0.31). No other factors differed significantly between the aspirin or clopidogrel resistant and sensitive patients in the cardiovascular group. Aspirin resistance was more common in patients with cardiovascular disease, and clopidogrel resistance in patients with cerebrovascular disease, although the difference was not significant. Our findings indicate that diabetes mellitus and an elevated level of lipoproteins could be risk factors for aspirin or clopidogrel resistance in patients with cerebrovascular diseases. Further studies should be conducted using larger patient cohorts with balanced groups of patients to investigate clinical aspects of antiplatelet resistance.

Abstract
The aim of this study was to assess the main effects and interaction between viral hepatitis C (HCV) coinfection and antiretroviral therapy (ART) by using a nonparametric ANOVA on direct and indirect markers of liver fibrosis in HIV-infected patients. The sample included 178 HIV patients aged from 23 to 65 (36% females). The following parameters were determined in blood of patients: hyaluronic acid, pro-matrix metalloproteinase-1, alanine aminotransferase, aspartate aminotransferase, and platelet count. The FIB-4 index was also calculated. The nonparametric ANOVA revealed no significant interaction between HCV coinfection and ART. This provides evidence for an independent contribution of each factor on promotion of the pathology. The results also demonstrated that the direct and indirect indicators of liver fibrosis are associated differently with the studied factors. Therefore, a combination of markers should be used for monitoring of liver fibrosis in HIV-infected patients.
