Physical activity among nursing students
Leona Cilar, Nina Preložnik, Gregor Štiglic, Dominika Jakl, Majda Pajnkihar, 2017, izvirni znanstveni članek

Opis: Introduction: Nurses need to encourage patients to lead a healthy lifestyle, hence it is important that as nursing students they are already aware of the importance of physical activity. The purpose of the study was to investigate the physical activities of nursing students. Aim: The aim of the study was to find out in what state physical activity of nursing students is and to find out what are their main reasons for lack of physical activity. Material and methods: We conducted a cross-sectional observational study using a mixed methods design. The quantitative data was collected using the survey method with a convenience sample of 123 students and used descriptive and inferential statistics for the analysis. For the qualitative data we used a Grounded Theory Method with semi-structured interviews on purposive samples of four students. Results and conclusions: In the quantitative part of this study we found a significantly higher proportion of outdoor physical activity in comparison to indoor physical activity (p < 0.001). The qualitative part contains the main categories of physical activity implementation, as well as three sub-categories: attitude to physical activity, barriers and incentives. Nursing students do not do physical activities regularly due to lack of time, obligations at the university, time of the year and finances.

The concept of Watson's carative factors in nursing and their (dis)harmony with patient satisfaction
Majda Pajnkihar, Gregor Štiglic, Dominika Jakl, 2017, izvirni znanstveni članek

Opis: Background: Constant reviews of the caring behavior of nurses and patient satisfaction help to improve the quality of nursing. The aim of our research was to explore relationships between the level of nursing education, the perception of nurses and nursing assistants of Watson's carative factors, and patient satisfaction. Methods: A questionnaire survey using a convenience sample of 1,098 members of nursing teams and a purposive sample of 1,123 patients in four health care institutions in Slovenia was conducted in August 2012. A demographic questionnaire and the Caring Nurse-Patient Interactions Scale (nurse version) were delivered to the nurses. A Hospital Consumer Assessment of Health Plans Survey was delivered to discharged patients. Data were analyzed using descriptive and inferential statistics. Results: Carative factor sensibility was related to the level of nursing education. Patients were satisfied with the care received from nurses, nursing assistants and hospitals, although we found differences between the perceptions of nurses and nursing assistants of carative factors and patient satisfaction. By comparing only the perceptions of nurses and nursing assistants of carative factors in health care institutions, differences were found for seven out of ten carative factors. Discussion: We did not find major significant differences between carative factors and level of nurse education, except in one carative factor. Differences in perceptions of carative factors between health care institutions are probably the result of different institutional factors. The results can be of great benefit to nurse administrators and educators, indicating the factors that must be taken into account for enhancing patient satisfaction. Emphasis on caring theories should be placed in nursing education and their application in nursing practice.

Contribution of temporal data to predictive performance in 30-day readmission of morbidly obese patients
Petra Povalej, Zoran Obradović, Gregor Štiglic, 2017, izvirni znanstveni članek

Opis: Background: Reduction of readmissions after discharge represents an important challenge for many hospitals and has attracted the interest of many researchers in the past few years. Most of the studies in this field focus on building cross-sectional predictive models that aim to predict the occurrence of readmission within 30-days based on information from the current hospitalization. The aim of this study is demonstration of predictive performance gain obtained by inclusion of information from historical hospitalization records among morbidly obese patients. Methods: The California Statewide inpatient database was used to build regularized logistic regression models for prediction of readmission in morbidly obese patients (n = 18,881). Temporal features were extracted from historical patient hospitalization records in a one-year timeframe. Five different datasets of patients were prepared based on the number of available hospitalizations per patient. Sample size of the five datasets ranged from 4,787 patients with more than five hospitalizations to 20,521 patients with at least two hospitalization records in one year. A 10-fold cross validation was repeted 100 times to assess the variability of the results. Additionally, random forest and extreme gradient boosting were used to confirm the results. Results: Area under the ROC curve increased significantly when including information from up to three historical records on all datasets. The inclusion of more than three historical records was not efficient. Similar results can be observed for Brier score and PPV value. The number of selected predictors corresponded to the complexity of the dataset ranging from an average of 29.50 selected features on the smallest dataset to 184.96 on the largest dataset based on 100 repetitions of 10-fold cross-validation. Discussion: The results show positive influence of adding information from historical hospitalization records on predictive performance using all predictive modeling techniques used in this study. We can conclude that it is advantageous to build separate readmission prediction models in subgroups of patients with more hospital admissions by aggregating information from up to three previous hospitalizations.

Analyzing information seeking and drug-safety alert response by health care professionals as ew methods for surveillance
Alison Callahan, Igor Pernek, Gregor Štiglic, Jurij Leskovec, Howard Strasberg, Nigam Haresh Shah, 2015, izvirni znanstveni članek

Opis: Background: Patterns in general consumer online search logs have been used to monitor health conditions and to predict health-related activities, but the multiple contexts within which consumers perform online searches make significant associations difficult to interpret. Physician information-seeking behavior has typically been analyzed through survey-based approaches and literature reviews. Activity logs from health care professionals using online medical information resources are thus a valuable yet relatively untapped resource for large-scale medical surveillance. Objective: To analyze health care professionals% information-seeking behavior and assess the feasibility of measuring drug-safety alert response from the usage logs of an online medical information resource. Methods: Using two years (2011-2012) of usage logs from UpToDate, we measured the volume of searches related to medical conditions with significant burden in the United States, as well as the seasonal distribution of those searches. We quantified the relationship between searches and resulting page views. Using a large collection of online mainstream media articles and Web log posts we also characterized the uptake of a Food and Drug Administration (FDA) alert via changes in UpToDate search activity compared with general online media activity related to the subject of the alert. Results: Diseases and symptoms dominate UpToDate searches. Some searches result in page views of only short duration, while others consistently result in longer-than-average page views. The response to an FDA alert for Celexa, characterized by a change in UpToDate search activity, differed considerably from general online media activity. Changes in search activity appeared later and persisted longer in UpToDate logs. The volume of searches and page view durations related to Celexa before the alert also differed from those after the alert. Conclusions: Understanding the information-seeking behavior associated with online evidence sources can offer insight into the information needs of health professionals and enable large-scale medical surveillance. Our Web log mining approach has the potential to monitor responses to FDA alerts at a national level. Our findings can also inform the design and content of evidence-based medical information resources such as UpToDate

From virtual library over dictum and intel until refine
Vladimir Šimunović, Hans-Günther Sonntag, Richard Marz, Maja Ostojić, Axel Horsch, Bojana Filej, Danica Železnik, Ana Marušić, 2008, pregledni znanstveni članek

Opis: The purpose of this paper is to recall how we, medical teachers in Bosnia-Herzegovina (BH), coped with the challenge of reform in higher education and to analyze what in our doing was fashion, which trends we have chosen to follow, and what were the real, substantial and tangible results of our work. Financial support for reform across the board came through the Trans-European Program for Co-operation in Higher Education in Central and Eastern Europe (Tempus), and, since 1997, the five schools of medicine in Bosnia and Herzegovina partnered with academic institutions from nine EU countries in seven granted Tempus projects. The results were tangible: a network of medical libraries was established; medical schools were assessed internally and externally; several important documents were drafted and agreed on; a core group of faculty from Bosnia and Herzegovina was trained in new teaching methods; and research was done and published. Not less important,there were also some less tangible, but perhaps even more important fruits of this cooperation. A sense of trust was established, which is essential for any future collaborative action. Representatives from all sides, previously divided by the war, had a chance to communicate with each other, dispelling some prejudices and regaining belief that it is possible to work together. This example of the schools of medicine of Bosnia and Herzegovina shows that higher education can be a favorable arena for reconciliation. Financial incentive can serve as a catalyst in the process and the presence of impartial partners (in our case, schools of medicine from the EU) proved beneficial for establishing and maintaining trust and good-will.The conclusion is that society rebuilding can be promoted indirectly,through formal education and professional engagement,not necessarily by pressing the “opposing” sides to talk about reconciliation and sign peace declarations.

Lower correlation between biceps femoris contraction time and maximal running speed in children than in adults
Jernej Završnik, Rado Pišot, Tadeja Volmut, Katja Koren, Helena Blažun, Peter Kokol, Janez Vošner, Boštjan Šimunič, 2016, izvirni znanstveni članek

Opis: Biceps femoris is a major propulsor muscle in sprinting and its contraction time negatively correlates to the running speeds of adults. Our aim was to compare age and gender-related correlations between vastus lateralis and biceps femoris contraction times and running speeds during a longitudinal study of 9- to 14-year old children. On a yearly basis we conducted vastus lateralis and biceps femoris tensiomyographic measurements of muscle contraction time and maximal running speeds measured during 7 meter sprints with flying starts using photocells in 107 children (53 boys). Vastus lateralis contraction time was not correlated with the running speed. However, biceps femoris contraction time was negatively correlated with the running speed only in boys after the age of 12.9 years (Pearson r ranges from -0.391 to -0.426; p < 0.002). It was concluded that biceps femoris contraction time is far less correlated with running speed than in adult athletes (Pearson r = -0.60); however, the correlation is gender and age-specific. It seems that the knee flexor and hip extensor, biceps femoris, is not as yet the major determinant of running speed in 9- to 14-year old children at that age.

Partial pressure of end-tidal carbon dioxide successful predicts cardiopulmonary resuscitation in the field - a prospective observational study
Miran Kolar, Miljenko Križmarić, Petra Klemen, Štefek Grmec, 2008, izvirni znanstveni članek

Opis: Introduction: The prognosis among patients who suffer out-of-hospital cardiac arrest is poor. Higher survival rates have been observed only in patients with ventricular fibrillation who were fortunate enough to have basic and advanced life support initiated early after cardiac arrest. The ability to predict outcomes of cardiac arrest would be useful for resuscitation. Changes in expired end-tidal carbon dioxide levels during cardiopulmonary resuscitation may be a useful non-invasive predictor of successful resuscitation and survival from cardiac arrest, and help in the termination of cardiopulmonary resuscitation in the field. Methods: This is a prospective observational study of 737 cases of victims who suffered sudden out-of-hospital cardiac arrest. The patients were intubated and the measurements of end-tidal carbon dioxide were performed. Data according to the Utstein criteria, demographic information, medical data and partial pressure of end-tidal carbon dioxide (petCO2) values were collected for each patient in cardiac arrest, by the emergency physician. We presumed that an end-tidal carbon dioxide level of 1.9 kPa (14.3 mmHg) or more after 20 minutes of standard advanced cardiac life support would predict restoration of spontaneous circulation (ROSC). Results: Partial pressure of end-tidal carbon dioxide after 20 minutes of advanced life support averaged 0.92+/- 0.29 kPa (6.9mmHg +/- 2.2 mmHg) in patients who did not have ROSC and 4.36 +/-1.11 kPa (32.8 mmHg +/- 9.1 mmHg) in those who did (p<0,001). End-tidal carbon dioxide values of 1.9 kPa (14.3 mmHg) or less discriminated between the 402 patients with ROSC and 335 patients without ROSC. When a 20-minute end-tidal carbon dioxide value of 1.9 kPa (14.3 mmHg) or less was used as a screening test to predict ROSC, the sensitivity, specificity, positive predictive value, and negative predictive value were all 100 percent. Conclusions: Measurements of end-tidal carbon dioxide levels of more than 1.9 kPa (14.3 mmHg) after 20 minutes should be used to accurately predict ROSC. End-tidal carbon dioxide levels should be monitored during cardiopulmonary resuscitation and considered a useful prognostic value for determining the outcome of resuscitative efforts and termination of cardio-pulmonary resuscitation in the field.

Capnometry in suspected pulmonary embolism with positive D-dimer on the field
Tadeja Hernja Rumpf, Miljenko Križmarić, Štefek Grmec, 2009, izvirni znanstveni članek

Opis: Introduction: Pulmonary embolism (PE) is one of the greatest diagnostic challenges in prehospital emergency setting. Most patients with suspected PE have a positive D-dimer and undergo diagnostic testing. Excluding PE with additional non-invasive tests would reduce the need for further imaging tests. We aimed to determine the effectiveness of combination of clinical probability and end-tidal carbon dioxide (PetCO2) for evaluation of suspected PE with abnormal concentrations of D-dimer in prehospital emergency setting. Methods: We assessed clinical probability of PE and PetCO2 measurement in 100 consecutive patients with suspected PE and positive D-dimer in the field. PetCO2 > 28 mmHg was considered as the best cut-off point. PE was excluded or confirmed by hospital physicians in the University Clinical Center Maribor by computer tomography (CT), ventilation/ perfusion scan echocardiography and pulmonary angiography. Results: PE was confirmed in 41 patients. PetCO2 had a sensitivity of 92.6% (95% CI, 79 to 98%), a negative predictive value of 94.2 % (95% CI, 83 to 99%), a specificity of 83 % (95% CI, 71 to 91%) and a positive predictive value of 79.2% (95% CI, 65 to 89%). Thirty-five patients (35%) had both a low (PE unlikely) clinical probability and a normal PetCO2 (sensitivity: 100%, 95% CI: 89 to 100%) and twenty-eight patients (28%) had both a high clinical probability (PE likely) and abnormal PetCO2 (specificity: 93.2%, 95% CI: 83 to 98%). Conclusions: The combination of clinical probability and PetCO2 may safely rule out PE in patients with suspected PE and positive D-dimer in the prehospital setting.

Insights into population health management through disease diagnoses networks
Keith Feldman, Gregor Štiglic, Dipanwita Dasgupta, Mark Kricheff, Zoran Obradović, Nitesh Chawla, 2016, izvirni znanstveni članek

Opis: The increasing availability of electronic health care records has provided remarkable progress in the field of population health. In particular the identification of disease risk factors has flourished under the surge of available data. Researchers can now access patient data across a broad range of demographics and geographic locations. Utilizing this Big healthcare data researchers have been able to empirically identify specific high-risk conditions found within differing populations. However to date the majority of studies approached the issue from the top down, focusing on the prevalence of specific diseases within a population. Through our work we demonstrate the power of addressing this issue bottom-up by identifying specifically which diseases are higher-risk for a specific population. In this work we demonstrate that network-based analysis can present a foundation to identify pairs of diagnoses that differentiate across population segments. We provide a case study highlighting differences between high and low income individuals in the United States. This work is particularly valuable when addressing population health management within resource-constrained environments such as community health programs where it can be used to provide insight and resource planning into targeted care for the population served.

Microorganisms with claimed probiotic properties: an overview of recent literature
Sabina Fijan, 2014, pregledni znanstveni članek

Opis: Probiotics are defined as live microorganisms, which when administered in adequate amounts, confer a health benefit on the host. Health benefits have mainly been demonstrated for specific probiotic strains of the following genera: Lactobacillus, Bifidobacterium, Saccharomyces, Enterococcus, Streptococcus, Pediococcus, Leuconostoc, Bacillus, Escherichia coli. The human microbiota is getting a lot of attention today and research has already demonstrated that alteration of this microbiota may have far-reaching consequences. One of the possible routes for correcting dysbiosis is by consuming probiotics. The credibility of specific health claims of probiotics and their safety must be established through science-based clinical studies. This overview summarizes the most commonly used probiotic microorganisms and their demonstrated health claims. As probiotic properties have been shown to be strain specific, accurate identification of particular strains is also very important. On the other hand, it is also demonstrated that the use of various probiotics for immunocompromised patients or patients with a leaky gut has also yielded infections, sepsis, fungemia, bacteraemia. Although the vast majority of probiotics that are used today are generally regarded as safe and beneficial for healthy individuals, caution in selecting and monitoring of probiotics for patients is needed and complete consideration of risk-benefit ratio before prescribing is recommended.
