Mapping the areas of research on intellectual capital throughout a period of dynamic environmental changes

Theoretical background: Intellectual capital is perceived as a global economy driving factor. Many researchers highlight that it is an ingredient improving the functional gear of almost any organisation. Some voices have simultaneously appeared in scientific discussions claiming that the concept of intellectual capital management may not be fully applicable, either in conditions of economic downturn or during turbulent changes. A whole spectrum of external factors then come to the floor, affecting the situation of a company, while the periods of economic perturbations discourage investments in human resources and hamper HR initiatives. Therefore, in these changing economic conditions, a question arises about the rationale for and the directions of the development on the research on intellectual capital, and the concept itself undergoes a practical verification of suitability and usefulness. This is a particularly interesting field of research because the transformations, which take place in the environment of enterprises, create specific expectations, which should be met within the framework of ongoing research projects on the intellectual capital.Purpose of the article: The aim of this article is to identify the dominant topical trends and networks of research directions in the subject of intellectual capital and their changes over time. The study attempts to illustrate these changes.Research methods: Having employed the text mining method, nearly 5,000 scientific articles on intellectual capital were analysed. Consequently, this extensive literature review enabled mapping of the network of links among the research directions in this area.Main findings: The results of the study have provided a fairly deep insight into the trends in the research on intellectual capital over the years. The results also reflect the vastness of the subject and the scope of the issues addressed over the past and present years. The interest in the concept of intellectual capital management continues and the dynamics of changes in the environment of the modern enterprise is not at all insignificant. The clusters, identified in the research on intellectual capital, have been opening new theoretical, pragmatic and methodological horizons. The analysis, carried out within the study network, confirmed the multifaceted nature of the network of research directions in the area of intellectual capital. In addition, the new research trends, which have been emerging in this area, clearly respond both to the dynamic changes in the business environment and to the doubts about the scale of activities, undertaken with regard to the intellectual capital management. Thus, in this situation, the periods of crisis and instability appear on one hand as a serious threat to the issue of intellectual capital management, while on the other, they can be perceived as an opportunity to renew the existing management concepts.Theoretical background: Intellectual capital is perceived as a global economy driving factor.

Computed tomography-guided percutaneous radiofrequency and laser ablation for the treatment of osteoid osteoma : long-term follow-up from 5 to 10 years

Purpose: The impact of computed tomography (CT)-guided, percutaneous radiofrequency ablation and interstitial laser ablation (ILA) on the management of patients with osteoid osteoma was studied. This was carried out by assessing immediate and long-term clinical outcomes, the complication rate, and repeat therapy effectiveness in recurrent patients who have already experienced percutaneous ablation. Material and methods: Consecutive patients with osteoid osteoma were assessed before the interventional treatment in a single centre from 2010 to 2015. Patient demographics, complications, and recurrence were recorded. The pain was evaluated with Visual Analogue Scale (VAS). Percutaneous procedures were performed by means of radiofrequency thermoablation or ILA. Epidural or regional anaesthesia in the CT suite was applied in all procedures. Success, whether primary or secondary, was measured as complete pain relief without evidence of recurrence after the first or second procedure, respectively. Osteoid osteoma characteristics, procedure overview, and technical success were looked for in pre-procedural and procedural scans. Results: Eighty-three per cent of osteoid osteomas were located in lower extremities, 56% of tumours were intracortical, and 83% of osteoid osteomas were extra-articular. The mean pre-procedure VAS score was 8.5 ± 0.8, while the overall primary success rate of radiofrequency thermoablation and ILA was 87.5%. No major complications were noted. The mean follow-up period for patients in was 7.5 years (5.0-10.2 years). Conclusions: Percutaneous, CT-guided thermoablation proved to be effective and should become the method of choice in osteoid osteoma treatment because of its minimal invasiveness. Our results show that there is no risk of very late recurrence after achieving primary and secondary treatment success

Tension pneumothorax as a severe complication of endobronchial ultrasound-guided transbronchial fine needle aspiration of mediastinal lymph nodes

This article presents a case report of a patient suffering from bullous emphysema and chronic obstructive pulmonary disease, who was diagnosed with tension pneumothorax after undergoing endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). Tension pneumothorax is a severe but rare complication of EBUS-TBNA. It can result from lung injury caused by the biopsy needle or, in patients suffering from bullous emphysema, from spontaneous rupture of an emphysematous bulla resulting from increased pressure in the chest cavity during cough caused by bronchofiberoscope insertion. The authors emphasize that patients should be carefully monitored after the biopsy, and, in the case of complications, provided with treatment immediately in proper hospital conditions. Patients burdened with a high risk of complications should be identified before the procedure and monitored with extreme care after its completion

Stability of ABR Wave V threshold in early hearing diagnostics in children from selected groups at risk of congenital hearing loss

Introduction: Upon hearing that the “little” patient has trouble with hearing, we are mostly interested in the level of his hearing threshold. When the child is in the first year of life, results can only be achieved by means of ABR test. Subsequent control tests, especially in children from the hearing loss risk groups selected in this study, show that the obtained outcomes are subject to fluctuations. Their fluctuating nature is manifested by the instability of wave V threshold in subsequent diagnostic periods. Such variability often delays the implementation of the appropriate proceeding. Knowledge of the dissimilarity of behavior of the wave V threshold occurring in individual groups at risk of hearing loss allows for the correct interpretation of the obtained results, and thus, effective therapeutic measures. Aim: The aim of the paper is to analyze the stability of wave V threshold during the first year of life in children from selected risk groups for congenital hearing disorders. Material and methods: From the patient population of 2,114 individuals examined in 2015–2016 at a reference center participating in the Universal Neonatal Hearing Screening Program in 2015–2016, the results of 250 children were subjected to retrospective analysis. Furthermore, 4 groups of little patients were formed (children with Down syndrome; children with other diseases or damage to the nervous system; children with cleft palate or cleft lip and cleft palate; children with congenital cytomegaly) in whom diagnostic practice revealed variable results of the wave V threshold. We analyzed the results of tests obtained during the first year of the child’s life divided into 4 diagnostic periods. Results: The highest percentage of instability in the established threshold of wave V between individual diagnostic periods occurred in the group of children with cleft palate or cleft lip and cleft palate. In the group of children with Down syndrome, it was observed that the instability of the ABR test results decreased over time. In the group of children with other diseases or damage of the nervous system, the highest percentage of the lack of stable ABR wave V thresholds was observed between the 1st and 2nd as well the 1st and 4th diagnostic periods. On the other hand, in the group of children with congenital CMV, there was a relatively low percentage of instability of results. Conclusions: (1) Although the ABR test is a diagnostic standard, in particular groups of patients the study is burdened with high variability of measurement results in subsequent diagnostic periods. Such a group of patients are children with cleft palate or cleft lip and cleft palate; therefore, it must receive particular attention in treatment planning; (2) in selected groups at risk of hearing loss, due to the high percentage of children with hearing impairment (70%), the validity of performing newborn hearing screening tests was confirmed
