Premature ventricular contraction (PVC) is a frequent kind of arrhythmia that affects around 1% of the general population. While PVC most frequently impairs ventricular function in structurally normal heart, retrograde ventriculo‐atrial conduction can occur in people with PVC. These retrograde atrial activations may mimic pulmonary vein‐derived atrial ectopies. As a result, PVC may raise the risk of atrial fibrillation (AF) by retrograde ventriculo‐atrial conduction. The Four‐Dimensional Automated Left Atrial Quantification (4D Auto LAQ) tool is a left atrial analytical approach that utilizes three‐dimensional volume data to quantify the volume, as well as LA longitudinal and circumferential strains. The purpose of this study was to determine if clinical diagnosis of PVC is connected with abnormal LA function as determined by LA strain evaluation utilizing a 4D Auto LAQ compared to the healthy population.

Premature ventricular complex (PVC) is common in general population. The atrial conduction time (ACT) represents the interval between electrocardiographic P wave and atrial mechanical contraction, and the prolongation of ACT called atrial electromechanical delay (EMD). In the present study, we investigated atrial conduction parameters through echocardiography in patients with frequent PVC. The study involved 54 patients with PVC and 54 healthy volunteers as a control group. A comprehensive echocardiographic examination was done. The time difference between the onset of the p wave and septal Am wave was the PA septal, the time difference between the onset of the p wave and the lateral Am wave was the PA lateral, and the time difference between the onset of the p wave and the tricuspid annulus Am wave was the PA tricuspid. The interatrial EMD was the time difference between the PA lateral and the PA tricuspid, the left atrial (LA) intraatrial delay was the time difference between the PA lateral and the PA septal and the right atrial (RA) intraatrial delay was the time difference between the PA septal and the PA tricuspid. LA anterior-posterior dimension and LA maximum volume were significantly larger in the patient group. Left intraatrial EMD, right intraatrial EMD, and interatrial EMD were significantly longer in the patient group. PA lateral, PA septal, PA tricuspid durations were significantly prolonged in the patient group. Atrial conduction times were prolonged in patients with frequent PVC. Type of funding sources: None.

Background: Supernumerary teeth (ST) represent one of the most common developmental anomalies among humans. Objective: In this study, we set a goal to investigate ST prevalence in the Bosnian and Herzegovinian population along with characteristics and complications that ST can cause. Methods: This retrospective study was based on panoramic radiographs, CBCT images, and dental records. Analyzed ST characteristics were: type, morphology, location, eruption state, location in the arch, orientation, and associated clinical complications. Statistical analysis included univariate analysis and bivariate analysis using Fisher’s exact test with a confidence interval of 95% (p<0.05). Results: On a sample of 10.237 patients, ST teeth appear in 100 patients with a prevalence of 0.98%. Out of 138 analyzed ST mesiodens was the most frequent (43.47%). The most common location of the ST was maxilla (77.53%). The majority of ST were impacted (90.5%) but with no complications (71.7%). There was statistically significant relationship (p<0.001) between the type of ST and location (mesiodens and distomolars were mostly found in the maxilla). The relationship between ST type and morphology was also statistically significant (p<0.001)–mesiodens was associated with conical morphology, parapremolar with supplementary, and distomolar with tuberculate morphology. The occurrence of ST-associated retention of adjacent teeth was correlated to the type of tooth (p<0.001) Conclusion: The present study found prevalence of ST in B&H population to be low. Although associated pathology was not high early diagnosis allows optimal patient management which reduces later complications.

The paper analyzes the last Yugoslav television series A Better Life (Bolji život) the broadcast of which ended when the war had begun on the territory of the SFRY. More than thirty years after the end of the first broadcast of the series, it is still popular in Croatia, Bosnia and Herzegovina and Serbia, which is noticeable through numerous reruns, but also popularity on social networks, as well as numerous quotes from the series that are used in colloquial speech. The paper presents the content of the series and the main characters, as well as the most important secondary characters, briefly explains the then political and media situation in the different republics of the SFRY, which was completely uneven, which led to numerous antagonisms between nations, so in this context the series A Better Life was singled out as a series that was equally followed by citizens in all the republics, which was a phenomenon. In the context of today, the series is analyzed through the prism of Yugonostalgia, and the content of the series is analyzed through several themes that appear in the series: everyday life and rituals, dealing with the consequences of the economic crisis, the conflict between rural and urban among the residents of Belgrade, i.e. the so-called old Belgraders and so-called newcomers.Certain stereotypes appeared in the series, primarily gender stereotypes, that is, the roles of men and women in society were repeatedly pointed out through the dialogues. Although at the time of filming of Better Life, inter-ethnic relations in SFRY were in crisis, the screenwriter skilfully avoided national stereotypes, although they appeared in several scenes, which is also included in the analysis of the series. Although the series depicts a politically turbulent time, nowadays it is viewed almost romantically, as a chance for a lost better life and missed opportunities.

Enterprise resource planning (ERP) systems have become the most important tool for integrating businesses and achieving the “once only” principle in data entry, which contributes to resource efficiency, the enhancement of numerous organizational processes and capabilities, and, ultimately, improved business performance. In this study, we examine the ERP system’s quality as the company’s dynamic capability, contributing to business performance according to the dynamic capability perspective. Thus, we incorporate theoretical mechanisms into the model of the ERP system’s dimensions as a function of financial and non-financial organizational performance. We hypothesized that companies with a better ERP system, with all three dimensions, information, system, and services, will achieve better non-financial and financial performance. The model was tested using primary data collected using a survey method in the environment of a developing country, where the digital transformation of companies is still at a lower level. Structural equation modeling was employed for data analysis, and the results suggest a positive relationship between ERP system quality and both types of organizational business performance. The results indicate that not all dimensions have the same effect. The quality of information and service is particularly important for business performance until the system’s technical characteristics have no significant effect.

Helichrysum italicum (Roth) G. Don (Asteraceae), also known as immortelle, usually grows in the Mediterranean area. The composition of the essential oil (EO) of immortelle is a mixture of various aromatic substances, mainly monoterpenes and sesquiterpenes. Distillation is the most widely used method for extraction of EO immortelle, although the yield is very low (<1%). In this work, we aim to investigate how the use of different distillation methods affects the yield and chemical composition of immortelle EO. For this purpose, we applied two conventional methods: steam distillation (SD) and hydrodistillation (HD), and a modern (environmentally friendly) technique—microwave-assisted distillation (MAD). Wild immortelles from four different locations in Croatia were collected and carefully prepared for extraction. Each sample was then analyzed by gas chromatography–mass spectrometry (GC-MS). GraphPad Prisma statistical software was used to study the statistics between different groups of connections and analyze the data on the number of connections. The results show that HD gives a significantly higher yield (0.31 ± 0.09%) compared to MAD (0.15 ± 0.03%) and SD (0.12 ± 0.04%). On the other hand, the highest number of chemical compounds was identified with MAD (95.75 ± 15.31%), and most of them are subordinate compounds with complex structures. SD isolated EOs are rich in derived acyclic compounds with the highest percentage of ketones. The results show that the application of different distillation methods significantly affects the composition of the obtained immortelle EO, considering the yield of EO, the number of isolated, derived and non-derived compounds, chemotypes and compounds with simple (acyclic) and complex structures.
