Connectedness is a multidimensional human experience that is essential to successful aging. The aims of this cross-sectional study were to assess connectedness and self-perception of successful aging in older people, to examine whether there are differences in relation to basic characteristics, and to examine whether there is a connection between connectedness and self-perception of successful aging. The respondents were elderly people in the Republic of Croatia. Data were collected using two validated scales: Croatian versions of the Register–Connectedness Scale for Older Adults and the Self-Assessment Scale of Successful Aging. The study included 824 respondents, of which 319 (38.7%) were men and 505 (61.3%) were women. The median age was 72 years. The median connectivity of the respondents was 8.9 (IQR= 7.6–10.2), and the median rating of successful aging was 3.25 (IQR = 1–5). Spearman’s correlation coefficient ρ (p value) was 0.585 (<0.001). Connectivity was rated better by respondents with a higher level of education, who were married, resided in their own homes, used modern technologies, and were active in the community. There is a significant positive association between connectedness and the self-perception of successful aging overall, as well as in all individual connectedness domains.

Research has shown that glycemic variability increases the risk of the development of acute and chronic complications with diabetes. Accordingly, the assessment of glycemic variability is of great importance to determine the quality of life for people suffering from diabetes. Objective: To examine the connection between glycemic variability and the quality of life for people with type 1 diabetes who use self-monitoring blood glucose devices. Respondents and methods: 42 respondents participated in the research with an average age of 39.6, who are treated with intensified insulin therapy. For the purpose of glycemic variability assessment, an innovative uniGluko system is used, which enables the display of glycemia in a unique graphic interface in the form of numeric values within the last three months from which a glycemic variability index was calculated as well as a general information survey, a survey on the quality of life from the World Health Organization (WHOQOL – BREF) and a short questionnaire regarding illness perception (Brief – IPQ). Results: By usage of standard deviation as a glyemic variability measure, statistically significant results have been obtained and they demonstrate that lower glycemic variability is connected to better quality of life (rs=-0.4571; p=0.0023), higher satisfaction with health (rs=-0.3186; p=0.0398) and reduced impact of disease on emotional life (rs=0.4097; p=0.,0071). Lower glucose variability implies reduced impact of disease on everyday life (rs=0.3091; p=0.0464), reduced incidence of symptoms (rs=0.3441; p=0.0255), and patients’ sense that they have more control over disease (rs=-0.5185; p=0.0004). Conclusion: The glycemic variability has a negative impact on life quality and health of patients with diabetes type 1.

This study aimed to examine the impact of personality on glycemic regulation in adult patients with type 1 diabetes mellitus (T1DM). The study group consisted of subjects with T1DM, who were ≥ 18 years of age. The study was conducted in two phases: At baseline, subjects completed the Croatian version of the International Personality Item Pool scale (IPIP50s) and a questionnaire designed to gather socioeconomic data, duration of diabetes, presence of chronic complications, presence of cardiovascular risk factors, frequency, and type of pre-existing hypoglycemic episodes per week. Blood and urine samples were collected and body mass index (BMI) was calculated. Each participant was provided with the intermittently scanned glucose monitoring system (isCGM) Freestyle Libre. During the second visit (3 months from the start of the trial), glycemic parameters were collected from the reports generated from the Freestyle Libre system. Estimated glycated hemoglobin (HbA1c) values were significantly lower after three months compared to baseline HbA1c (Wilcoxon test, p < 0.001). An inverse correlation between the number of daily scans and degree of extraversion among subjects was observed, e.g., higher degrees of extraversion resulted in lower numbers of daily scans, while lower degrees of extraversion, i.e., introvertedness, resulted in higher numbers of daily scans (Rho = −0.238 p = 0.009). There was a positive correlation between emotional stability and time spent in hypoglycemia (Rho = 0.214; p = 0.02). In addition, a shorter duration of diabetes was associated with higher percentages of TIR and vice versa (p = 0.02). Investigating personality traits can be a useful tool for identifying patients predisposed to hypoglycemia and lower scanning frequency. Patients with a longer history of T1DM require closer follow-up and should be re-educated when necessary.

Extract of Alchemilla vulgaris L. was investigated as eco-friendly corrosion inhibitor for aluminium in 3 % NaCl using electrochemical techniques. According to the results, inhibition efficiency increases with the increase concentration of extract and the highest efficiency (~80 %) is recorded for the maximal concentration of extract (1.0 g L–1). The inhibition activity of extract occurs by the spontaneous physisorption (ΔG ≈ –16 kJ mol–1) on active sites of aluminium surface that follows Freundlich isotherm. Polarization curves showed that Alchemilla vulgaris L. extract act s a mixed-type inhibitor. The effect of temperature on the aluminium corrosion and inhibition action of extract was studied and the result showed that the corrosion rate increased and the inhibitor efficiency decreased with increase of temperature. The calculated values of the activation energy confirmed presence of inhibitive Alchemilla vulgaris L. extract on aluminium surface.

BACKGROUND Timely and efficient recall of products known or suspected to be non-conforming is an important measure in the prevention of adverse events and in patients' safety. Product recall in the transfusion service is regulated by professional standards and legal acts, but publications presenting results related to the implementation of these procedures are quite rare. MATERIALS AND METHODS Data from the Croatian Institute of Transfusion Medicine (CITM) on the procedures of product recall during an 11-year period (2000-2010) were retrospectively analyzed. Reasons for product recall, their frequency, level of severity and efficiency of the procedures are presented and discussed. RESULTS During the study period, there were 245 procedures of product recall, for an average of 22 (18-29) procedures/year, all of low extent (1-25 products). Recall was required for 1/3,571 blood products issued, while the frequency of laboratory test report recalls was 1/5,447 patients. The leading reasons for product recall were suspected bacterial contamination of blood products (30.2%) and suspected or demonstrated non-conformity of laboratory test reports (28.6%). In total, 99 (40.4%) product recalls were categorized as class I, 30 (12.2%) as class II and 116 (47.3%) as class III. DISCUSSION According to the available literature data, the product recall procedures were performed quite infrequently by the CITM and were of low extent. There was a remarkable decreasing trend in the rate of product recall due to non-conformities or errors made at the CITM, along with a constant or increasing rate of recalls because of biological variability of blood products.

The aim of this review was to provide an overview of researchinto the relationship between empathy and bullying. Thereforethe review indicated a number of researches that show differenteffects of empathy on bullying, regarding the type of bullying,roles in bullying behavior, as well as gender. From a review ofresearch it may be concluded that empathy significantly contributesto a reduction in various forms of violence. Most researchindicates the importance of the affective component of empathycompared to the cognitive component. The results of researchinto the relationship of empathy and its role in bullying behaviorwere less consistent. For this reason, the review highlightedmethodological difficulties in the study of bullying and empathy.  Conclusion  – In conclusion it could be said that most studiesshow a negative correlation between empathy and various typesof violence. Furthermore, it is evident that different componentsof empathy have differing degrees of influence in direct and indirectforms of violent behavior.
