Background: Stroke is a major health problem around the world. Several studies have examine the influence of ambient temperature on incidence of stoke, but they reported different results for different types of stroke and different geographical regions. Hence, effect of ambient temperature is still much of interest, when focusing on ischemic stroke (IS) in regions that have not been examined yet. The aim of our study is to analyse association between IS incidences and short, delayed and cumulative effect of average daily ambient temperature, humidity and pressure in central Europe. To the best of our knowledge, this is the first IS study conducted between 45° and 50° latitude where large part of Central European population resides. Methods: We linked daily hospitals’ admission data for whole population and separately for two specific age groups with ambient temperature data. We considered patients coming from Ljubljana basin and its immediate surrounding. Data were gathered daily from January 2012 to December 2017. To measure the effect of average ambient temperature, humidity and pressure we used generalized linear model with a log-link-function and a Poisson distribution. Results: The results of our study show a statistically significant immediate, delayed and cumulative effects of ambient temperatures on IS incidence for the whole population and the population older than 65 years. Specifically, 1 °C reduction in ambient temperature on a given day (Lag 0) increases the IS risk for approximately 5‰ (all population) or 6‰ (population older than 65 years). Similar effects were found for lags from 1 to 6. Analysis of time windows from 0 to 1 days up to 0–28 days also show statistically significant cumulative effect for the same two age groups. IS incidence was not found to be significantly related to pressure or humidity in any group. Conclusion: The findings of this study may help healthcare authorities in central Europe improve existing stroke prevention measures and raise public awareness.

Background: A nationwide study was conducted to explore the short term association between daily individual meteorological parameters and the incidence of acute coronary syndrome (ACS) treated with coronary emergency catheter interventions in the Republic of Slovenia, a south-central European country. Method: We linked meteorological data with daily ACS incidence for the entire population of Slovenia, for the population over 65 years of age and for the population under 65 years of age. Data were collected daily for a period of 4 years from 1 January 2008 to 31 December 2011. In line with existing studies, we used a main effect generalized linear model with a log-link-function and a Poisson distribution of ACS. Results and Conclusions: Three of the studied meteorological factors (daily average temperature, atmospheric pressure and relative humidity) all have relevant and significant influences on ACS incidences for the entire population. However, the ACS incidence for the population over 65 is only affected by daily average temperature, while the ACS incidence for the population under 65 is affected by daily average pressure and humidity. In terms of ambient temperature, the overall findings of our study are in line with the findings of the majority of contemporary European studies, which also note a negative correlation. The results regarding atmospheric pressure and humidity are less in line, due to considerable variations in results. Additionally, the number of available European studies on atmospheric pressure and humidity is relatively low. The fourth studied variable—season—does not influence ACS incidence in a statistically significant way.

Clinical reasoning is a key attribute of nursing and midwifery professionals. As a part of the Erasmus plus project, we designed a study with the aim of exploring the understanding of clinical reasoning as a concept, experiences of teaching clinical reasoning and practices related to using clinical reasoning in nursing and midwifery. A qualitative study was carried out using the World Café method, involving 44 participants from five European countries. The participants represented diverse professional backgrounds, including nurses, midwives and lecturers. Our analytical approach was based on a thematic analysis. We categorized the data into three main categories, namely, “Spiral of thinking”, “The learning and teaching of a way of thinking” and “Clinical reasoning in real life”, all under an overarching theme, “Learning a way of thinking”. This study highlighted areas of learning and teaching which can be improved in current nursing and midwifery education. Furthermore, it identified barriers, facilitators and practices from five European countries which can be used in the further development of nursing and midwifery curricula and courses with the aim of enhancing clinical reasoning competence and ultimately improving patient care.

The influence of several meteorological parameters on acute myocardial infarction (AMI) incidences with immediately and/or delayed effects has been widely reported. It remains unknown whether the individual AMI subtypes reveal similar patterns. To date, generally seasonal variation in ST elevation MI (STEMI) has been investigated. However, these approaches couldn’t detect the effects of changes in multiple meteorological variables on STEMI incidence within a specific season. Therefore, the aim of our study is to explore immediate, delayed and cumulative effects of average daily temperature, atmospheric pressure and humidity on nation-wide STEMI hospital admissions. We linked daily hospitals’ STEMI admission data with meteorological stations’ data according to the patient’s permanent residence. Subsequently, a multivariate analysis based on a main effect generalised linear model, assuming a log-link function with a Poisson distribution, was conducted. With the help of lags, we were able to analyse delayed effects, while the cumulative effects of specific meteorological variables were analysed utilising time windows. As a result, we confirmed immediate and delayed negative effect of low temperature and low relative humidity for all observed lags as well as cumulative average effects of low temperature and low relative humidity for all observed time windows. However, no delayed, single-day effect for atmospheric pressure was detected. Nevertheless, the cumulative average effect was confirmed in all time windows suggesting that prolonged low pressure influences the incidence of STEMI. A novelty of our approach is the comparative examination of immediate, delayed and cumulative effect of specific meteorological variables on the incidence of STEMI. This approach enables us to gain a new insight into the phenomenon studied.

Background/Objectives: Providing nursing care for individuals with intellectual and developmental disabilities can be challenging for nursing students, often perceived as stressful, demanding, and, at times, unpleasant. This study aimed to describe the experiences of students in their interactions and provision of nursing care for people with intellectual and developmental disabilities. Methods: A qualitative descriptive study was conducted. Fourteen self-reflections from nursing students were analysed by using qualitative content analysis. Results: The findings indicate that students experience contact and nursing care for individuals with intellectual and developmental disabilities as dynamic and varied. This process is characterised by transitions in communication and interaction, emotional transitions, and transitions in knowledge and understanding of caring and nursing care. Conclusions: Students encountered emotional, cognitive, and behavioural challenges when interacting with and providing care for individuals with intellectual and developmental disabilities. Their experience is described as multidimensional and demanding. Gaining insight into these experiences and understanding the students’ perspectives are essential for planning future theoretical and practical nursing education.

(1) Background: In recent decades, studies have reported on the increased cardiovascular risk associated with increased levels of air pollutants, especially particulate matters (PM). It remains unclear whether the specific subgroups share the same involvement and whether the effect is delayed. (2) Methods: Data for acute coronary syndrome (ACS) incidences from 2008 to 2011 were gathered in two major medical centres in Slovenia. A time series analysis was conducted in which daily ACS incidence data were linked with daily concentrations of PM10 (PM with a median aerodynamic diameter less than 10 μm) using a well-established generalized linear model with a log link function and a Poisson distribution of ACS. We specifically focused on groups based simultaneously on age and gender. (3) Results: On the basis of the presented models, it appears that daily average concentrations of PM10 have a significant impact on ACS incidence for the entire population, with a higher impact on older populations and the highest impact on older men. The analysis of the delayed effect in PM10-related ACS incidences observed the strongest effect at a one day lag. (4) Conclusions: Our study detected the presence of a “rise and fall” lag pattern observed in three aforementioned population groups; however, no significant association was detected for women and younger populations.
