Autorica se u radu bavi Zbirkom narodnih nošnji naroda Europe Etnografskog muzeja, koja je formirana 2015. godine, a sadrži većinom pojedinačne predmete, fragmente i u manjoj mjeri komplete odjeće s ...područja Makedonije, Crne Gore, Srbije, Austrije i drugih europskih zemalja.
The paper deals with the Collection of traditional costumes of European countries of the Ethnographic Museum, which is formed in 2015 and contains mostly individual items, fragments and, to a lesser ...extent, sets of clothing from Macedonia, Montenegro, Serbia, Austria, and other European countries.
The paper addresses the issue of development of educational activities in the Ethnographic Museum in Zagreb throughout its first 100 years of activity. During the first years of operation of the ...Museum educational activities were evident primarily in the work of the curator Mirko Kus-Nikolajev, despite the fact that there was no conceptualised approach to educational activities in the Museum at the time. Several decades later, in the second half of the 20th century a conceptualised approach was formulated by the first museum educators: Aleksandra Sanja Lazarević and Nada Majanović. Today, the educational programme is currently being developed in accordance with the contemporary trends in museum education, which focuses on different groups of museum users and highlights the social responsibility of the Museum.
Rad se bavi razvitkom obrazovnoga djelovanja Etnografskoga muzeja u Zagrebu tijekom njegovih prvih 100 godina. U prvim godinama djelovanja Muzeja, iako nije postojao osmišljen pristup obrazovnim ...aktivnostima Muzeja, on se očituje prvenstveno u radu kustosa Mirka Kusa-Nikolajeva. Nekoliko desetljeća kasnije, u drugoj polovici 20. stoljeća, oblikuju ga prve muzejske pedagoginje Aleksandra Sanja Lazarević i Nada Majanović. Danas se razvija u skladu sa suvremenim tendencijama u muzejskoj edukaciji prema različitim skupinama korisnika naglašavajući društvenu odgovornost muzeja.
as a relatively high number of ST-segment elevation myocardial infarction (STEMI) patients develop major adverse cardiovascular events (MACE) following percutaneous coronary intervention (PCI), our ...aim was to determine the significance, and possible predictive value of QRS complex width and ST-segment elevation.
our patient sample included 200 PCI-treated STEMI patients, which were divided into two groups based on the following duration of symptoms: (I) less than 6 h, and (II) 6 to 12 h. For every patient, an ECG was performed at six different time points, patients were followed for up to six years for the occurrence of MACE.
the mean age was 60.6 ± 11.39 years, and 142 (71%) were male. The 6-12 h group had significantly wider QRS complex, higher ST-segment elevation, lower prevalence of ST-segment resolution as well as MACE prevalence (
< 0.05). ECG parameters, QRS width, and magnitude of ST-segment elevation were proved to be independent significant predictors of MACE in all measured time points (
< 0.05). Even after controlling for biomarkers of myocardial injury, these ECG parameters remained statistically significant predictors of MACE (
< 0.05).
our study highlights that wider QRS complex and a more pronounced ST-segment elevation are associated with longer total ischemic time and higher risk of long-term MACE.
Abstract Background and Aims In a population hospitalized for acute heart failure, about 20% are affected by acute kidney injury, a significant independent factor linked to increased mortality both ...during hospitalization and within one year. While existing research offers insights, crafting a precise model to predict mortality in heart failure cases remains a complex task, primarily due to the difficulties in pinpointing critical determinants and achieving high accuracy. The aim of our research was to assess the efficacy of serum creatinine and NT-proBNP levels as predictors for mortality in heart failure patients, using machine learning. Method In our retrospective cross-sectional study, we examined the records of 1,042 patients hospitalized due to acute heart failure at the Institute of Cardiovascular Diseases of Vojvodina, spanning the period from January 1, 2021, to December 31, 2022. The data was initially cleaned, after which we employed a Random Forest model for our analysis. The dataset was partitioned into a training subset, constituting 70% of the data, and a testing subset, comprising the remaining 30%. To achieve optimal precision, we ran the model 100 times. Key performance metrics, including mean sensitivity, specificity, accuracy, F1 score, Matthew's correlation coefficient (MCC), and the area under the Receiver Operating Characteristic (ROC) curve (AUC), were derived from the model to assess its efficacy. Results Following data cleansing, the dataset encompassed a total of 389 patients, of which 58% were male. The median age in this cohort was 71 years, with an interquartile range (IQR) of 63 to 79 years. Key laboratory findings included a median serum creatinine level of 111 µmol/L (IQR: 85-167 µmol/L) and a median NT-proBNP level of 6,589 pg/mL (IQR: 2,822-15,608 pg/mL). After the partition, the median number of patients in the training set was 272 and the testing set comprised 117 patients. The performance of the Random Forest model was characterized by a sensitivity of 0.530, specificity of 0.916, an overall accuracy of 0.856, and an F1 score of 0.516. The MCC stood at 0.439 with the AUC under the ROC curve being 0.713. Conclusion While the relatively low sensitivity observed in our model could be attributed to the generally lower levels of serum creatinine upon admission and the retrospective nature of the study, which may have influenced the model's ability to identify all true positive cases effectively, serum creatinine and NT-proBNP levels hold promise as effective predictors for mortality in heart failure patients.
In 2020, decreased emergency department (ED) visits and hospitalization rates during the COVID-19 outbreak were reported. There is no data about cardiovascular emergencies and mortality for the whole ...COVID-19 year.This study aimed to compare the rates of cardiology ED visits, hospital admissions, and intrahospital mortality between the pre-COVID-19 and COVID-19 years in a single high-volume center.The retrospective observational cross-sectional study analyzed data on the number of ED visits, hospital admissions by different cardiovascular diagnoses, and outcomes.A total of 11744 patients visited the cardiology ED in the pre-COVID-19 year compared with 9145 in the COVID-19 year, indicating an overall decrease of 22.1% (P = 0.02) (IR 78.76 versus 61.33; incidence rate ratios (IRR) 1.28, P = 0.00), with an observed decrease of 25.5% in the number of hospitalizations (33.1% versus 31.6%, P = 0.02). A marked decrease in hospitalizations for cardiovascular emergencies was observed for hypertensive heart disease (−72.8%, P < 0.0001), acute coronary syndrome (−17.8%, P < 0.0001), myocardial and pericardial diseases and endocarditis (−61.2%, P = 0.00), and valvular heart disease (−70.8%, P < 0.0001). In the COVID-19 year, patients had increased need for mechanical ventilatory support (7% versus 6.3%, P = 0.03) with no overall difference in intrahospital mortality (IR 2.71 versus 2.78, IRR 0.98, 95% CI 0.82-1.16, P = 0.39).Decreased ED visits and hospitalizations not just in outbreaks but through the whole COVID-19 year highlight the risk of continuous delay of needed care for emergency life-threatening cardiovascular diseases. Urgent comprehensive strategies that will address patient- and system-related factors to decrease morbidity and mortality and prevent collateral damage of the pandemic are needed.
