The aim of this study was to investigate the differences of young school children in the visual preferences of paintings from the 20th century. The study was conducted at 4 elementary schools around Split, Croatia. A total of 200 children participated in the study, of which 87 were girls and 113 were boys aged 6-10 years. Visual preference testing was conducted individually where pupils assessed, on a 5-point scale, the degree to which they liked 36 paintings that were presented in pairs on the computer screen. The results showed that pupils preferred paintings made before the 20th century and paintings without artistic value. Boys and girls equally prefer paintings from the 20th century, with the exception of surrealism, which boys preferred better. Pupils, irrespective of age, better prefer fauvism, pop art, and surrealism, as opposed to cubism and abstract art. Apparently, children prefer more fine lines with a distinctive motif, cleaner colors, and 3-dimensional diagrams of signs and space (fauvism, surrealism, pop art); and they less favored paintings from the 20th century where it is hard to perceive the spatial relationships, which are abstract or difficult to figuratively recognize (cubism, abstract painting).

Background: The primary objective of this study was to compare concomitant and hybrid therapy in the first line eradication treatment of Helicobacter pylori infection in Split-Dalmatia County, Croatia, in which clarithromycin resistance is above 20%. The secondary objective of the study was to determine and compare compliance and adverse events rate between these therapeutic protocols. Materials and methods: In an open-label, randomised clinical trial 140 patients total with H. pylori infection were randomly assigned to either concomitant (esomeprazole 40 mg, amoxicillin 1 g, metronidazole 500 mg, clarithromycin 500 mg, twice daily for 14 days) or hybrid (esomeprazole 40 mg and amoxicillin 1 g twice daily during 14 days with adding metronidazole 500 mg and clarithromycin 500 mg twice daily, in the last 7 days,) treatment group. Results: Eradication rates for concomitant group and hybrid therapy group were 84.1% (58/69) and 83.1% (59/71) respectively in the intention-to-treat analysis and 96.7% (58/60) and 95.2% (59/62) in per-protocol analysis. There was no significant difference between the groups (ITT analysis: P = 0.878; PP analysis: P = 0.675). Adverse events were more frequent in the concomitant group (33.3% vs 18.3%, P = 0.043). There was no difference among groups regarding compliance rate. Conclusion: Hybrid therapy has similar eradication rate as concomitant therapy, with lower adverse events rate. In the era of increasing antibiotic resistance, eradication regime with less antibiotic's usage, as hybrid therapy, should be reasonable first line treatment choice for H. pylori infection.

Background: Early detection and treatment of tuberculosis (TB) patients have been key principles of TB control. Therefore, it is important to understand the causes of delay and to estimate their magnitude in order to plan interventions that yield the maximum benefit. Methods: A total of 240 subjects aged ≥15 year with pulmonary TB were interviewed. Patient delay was defined as the period (in days) from the appearance of any symptoms to the first visit to a medical provider. Results: The median patient delay was 38 days. When using the median as a cut-off to define long patient delay, being an ex-smoker (P = 0.036), current smoker (P = 0.030), coughing (P = 0.021) and losing weight (P = 0.050) were found to be significant. Having high level of education (P = 0.014) was associated with short delay. Being an ex-smoker (P = 0.050, adjusted odds ratio (aOR) = 1.940, 95% CI 1.001–3.759), current smoker (P = 0.029, aOR = 2.077, 95% CI 1.076–4.012) and having a cough (P = 0.022, aOR = 2.032, 95% CI 1.108–3.727), were significant in multivariate logistic regression, while having high level of education remained associated with short delay (P = 0.016, aOR = 0.286, 95% CI 0.103–0.791). The most common reasons for delay were supposed influenza or symptoms improving over time (34.5%) and underestimated symptoms (32.9%). Conclusion: People with smoking habits and health-seeking behaviour that may favour advanced disease and prolonged infectiousness as well as people with the lowest level of education contributed to TB delay. To reduced patient delay, efforts should be made to increase TB knowledge, which has to be adjusted to the less-educated segments of the population. [ABSTRACT FROM AUTHOR]

Aim To investigate the association between parental war involvement and different indicators of psychosocial dis-tress in a community sample of early adolescents ten years after the war in Croatia 1991 -1995 Methods A total of 695 adolescents were screened with a self-report questionnaire assessing parental war involve-ment, sociodemographic characteristics, and alcohol and drug consumption. Personality traits were assessed with the Junior Eysenck Personality Questionnaire; depressive symptoms with the Children's Depression Inventory (CDI); and unintentional injuries, physical fighting, and bullying with the World Health Organization survey Health Behav-ior in School-aged Children. Suicidal ideation was assessed with three dichotomous items. Suicidal attempts were as-sessed with one dichotomous item. Results Out of 348 boys and 347 girls who were includ-ed in the analysis, 57.7% had at least one veteran parent. Male children of war veterans had higher rates of uninten-tional injuries (odds ratio [OR], 1.2; 95% confidence interval [CI], 0.56 to 2.63) and more frequent affirmative responses across the full suicidal spectrum (thoughts about death -OR, 2.1; 95% CI, 1.02 to 4.3; thoughts about suicide - OR, 5; 95% CI, 1.72 to 14.66; suicide attempts - OR, 3.6; 95% CI, 1.03 to 12.67). In boys, thoughts about suicide and un-intentional injuries were associated with parental war in-volvement even after logistic regression. However, girls were less likely to be affected by parental war involvement, and only exhibited signs of psychopathology on the CDI total score. Conclusion Parental war Involvement was associated with negative psychosocial sequels for male children. This rela-tionship is possibly mediated by some kind of identifica-tion or secondary traumatization. Suicidality and uninten-tional Injuries are nonspecific markers for a broad range of psychosocial distresses, which is why the suggested target group for preventive interventions should be veteran par-ents as vectors of this distress.

As high clarithromycin resistance (>20%) in the Split-Dalmatia region of Croatia hinders the treatment of H. pylori infection, the primary objective of this study was to compare concomitant quadruple with the tailored, personalized therapy as first-line eradication treatment of H. pylori. In an open-label, randomized clinical trial, 80 patients with H. pylori infection were randomly assigned to either concomitant (esomeprazole 40 mg, amoxicillin 1 gr, metronidazole 500 mg, clarithromycin 500 mg, twice daily for 14 days) or tailored therapy in accordance with the results of the antimicrobial susceptibility testing. Eradication status was assessed 4 weeks after treatment. Eradication rates were significantly higher in tailored group than in concomitant group both in intention-to-treat (70 vs. 92.5%, p = 0.010) and per-protocol (87.5 vs. 100%, p = 0.030) analysis in the setting of increasing antibiotic resistance (clarithromycin 37.5%, metronidazole 17.5%, dual resistance 10%). Adverse effects were more frequent in the concomitant group (32.5 vs. 7.5%, p = 0.006). Tailored therapy achieves higher eradication with a lower adverse events rate. With the increasing resistance of H. pylori strains to antibiotic treatment, eradication regimes with such characteristics should be strongly considered as a reasonable choice for first-line treatment.

The purpose of this paper was to interpret the usage of symbols in popular religion based on contemporary symbolic interactionism using the reference framework of the symbolic community. The strength of the chosen symbolic interactionist approach is primarily in the research of the role of different dimensions of the religious in understanding the meaning of popular religion in the symbolic community. The qualitative approach and the method of in-depth semi-structured interviews were employed in the research, which responded to the main goal of the research on the meanings the participants of the popular religion attach to the symbolic interactions. A deliberate sample was used for the selection of participants in the popular forms of celebrating the days of Our Lady of Vrpolje, Our Lady of Sinj, and Our Lady of Karavaj as well as the Guardians of Christ's grave in Vodice, Croatia. According to the results, popular religion, transmitted through visible signs, places believers in a position of physical contact with the supernatural world within a symbolic environment. To achieve this, popular religion displays a need for sacred images, words, sounds, signs, movements, smells. Believers in popular religion seek to establish as simple, intimate, and direct relationship with a deity as possible. The respondents' answers confirm that the experiential dimension of religiosity is lived primarily on a personal level that precedes the social dimension. For the participants, the religious community has a symbolic character in terms of creating strong bonds between members of society or a social group, especially within the symbolic meaning of a feast day.

Aim To assess physicians' knowledge and practices for obtaining patients' informed consent to medical procedures. Methods An anonymous and voluntary survey of knowledge and practices for obtaining informed consent was conducted among 470 physicians (63% response rate) working in 6 hospitals: 93 specialists in anesthesiology, 166 in internal medicine, and 211 in surgery. Results Only 54% physicians were acquainted with the fact that the procedure for obtaining consent was regulated by the law. Internists and surgeons were better informed than anesthesiologists (P = 0.024). More than a half of respondents (66%) were familiar with the fact that a law on patient rights was passed in Croatia; there were no differences among different specialties (P = 0.638). Only 38% of the physicians were fully informed about the procedure of obtaining consent. Internists and surgeons provided detailed information to the patient in 33% of the cases and anesthesiologists in 16% of the cases (P < 0.050). Internists reported spending more time on informing the patient than anesthesiologists and surgeons (P < 0.001). There were no differences in knowledge and practices for obtaining informed consent between physicians working in university and those working in community hospitals (P ≥ 0.05 for all questions). Conclusion Physicians in Croatia have no formal education on informed consent and implement the informed consent process in a rather formal manner, regardless of the type of hospital or medical specialty. Systemic approach at education and training at the national level is needed to improve the informed consent process. [ABSTRACT FROM AUTHOR]

Background: The aim of our study was to investigate the differences in beliefs, attitudes toward CAM, beliefs in afterlife and religiosity among the sample of psychiatrists, psychologists, and theologists. Relationship among these constructs could have impact on the concept of mental health., Subjects and Methods: Research was conducted in the Split urban area, Croatia, during 2017 on a sample of psychiatrists (n=51), psychologists (n=55), and theologists (n=25). Participants were presented a figure of the human body, which contained numbers identifying eight different regions of the body. Participants were asked to select which region best represents the location of the self, soul, and mind in the body. We used CAIMAQ (The Complementary, Alternative and Integrative Medicine Attitudes Questionnaire) which contains five subscales. The Afterdeath Beliefs Scale was used to measure the varieties of afterlife beliefs. Analyses showed that applied questionnaires have appropriate reliability and expected factor structure., Results: The most frequent locations of the Soul were 9 (37%, Not located in any centralized region in the body) and 5 (31% chest), whereas Self and Mind were mostly located in the head (43% and 73%). Psychiatrists and psychologists have average scores on positive pole of CAIMAQ but did not differ significantly (p>0.05). There were statistical differences between theologists and psychologists/psychiatrists on two subscales: "nutritional counseling and dietary/food supplements can be effective in the treatment of pathology" and "attitudes toward a holistic understanding of the disease" (p<0.05). There were significant correlations between religion and three CAIMAQ subscales. Although they were mostly religious, psychiatrists and psychologists had a higher average score on Annihilation than theologists. They also did not believe in body resurrection and connection between behavior during life and after death., Conclusion: The results of our study could have impact on the concept of mental health and in the future must be deeper evaluated within qualitative research methodology.

Aims: Suicidal ideation and sleep-related problems are associated with many common psychopathological entities in early adolescence. This study examined possible association between suicidal ideation and sleep-related problems., Methods: A cross-sectional study was performed in classroom settings at 840 early adolescents 11-13 years of age. Of those, 791 adolescents fully completed the data and thus represent an actual sample. Suicidal ideations were assessed with three dichotomous (yes/no) items: 'I often think about death'; 'I wish I was dead'; 'I often think about suicide.' A composite measure of perceived sleep-related problems was formed by combining items from the Junior Eysenck Personality Questionnaire (Do you find it hard to sleep at night because you are worrying about things?), Children Depression Inventory (It is hard for me to fall asleep at night), and two additional dichotomous questions (I often was not able to fall asleep because of worrying; At times I was not able to stay asleep because of worrying). This score mainly assessed difficulties in initiating or maintaining sleep., Results: A total of 7.1% adolescents reported suicidal ideation and 86.7% of them had sleep problems. Sleep-related problems were associated with any suicidal ideation and each type of ideation separately., Conclusion: This study suggests association of sleep problems and suicidal ideations in early adolescence. Therefore, clinicians should evaluate this population for sleep disturbances, as they might be a marker of increased risk for suicidality., (© 2013 Wiley Publishing Asia Pty Ltd.)

Background/aims: Suicidal ideations (SI) indicate and predict psychological distress. We examined the prevalence of SI among early adolescents and its association with parental war participation, personal, behavioral, and sociodemographic characteristics., Methods: We performed a cross-sectional questionnaire study on 803 12-year-old adolescents. Data were collected using a sociodemographic questionnaire, the Junior Eysenck Personality Questionnaire and Children Depression Inventory. Unintentional injuries, physical fighting, and involvement in bullying behavior were assessed using questions from the World Health Organization (WHO) survey Health Behavior in School-aged Children. Suicidal ideations were assessed with three dichotomous items., Results: There were no gender differences in SI prevalence. SI in males were associated with lower maternal education, crowded families, birth order, parental war participation, physical fighting, being bullied, and substance use. In females, we found associations with lower parental educational level, number of brothers, lower perception of the relationship with parents, parental relationship, family cohesion and parental control, negative attitude toward school, rare church attendance, fighting, and being bully or bullied. Depressive symptoms and SI were associated in both genders., Conclusions: SI showed gender-specific associations that may partially be explained with parental war involvement. These findings may have potentially important clinical and preventive implications.

Our aim was to explore and compare the job satisfaction between family physicians and hospital specialists in Split, Croatia. The survey was carried out in 2005 and 2006. A validated questionnaire was composed of two parts: 92 statements and questions about job satisfaction in the form of a Lickert scale (range 1-5) and eight questions concerning demographic issues. The questionnaire was completed and returned by 165 hospital specialists from the University Hospital and by 131 family physicians from the Split County. Response rate for family physicians was 39.81% and 41.46% for hospital specialists. Hospital doctors were divided in two groups: internal and surgical. There were no significant differences between family physicians and hospital specialists in total job satisfaction (F = 1.02; p = 0.41). Family physicians were more satisfied with their workplace conditions than internal medicine specialists (19.37 +/- 4.23 vs. 17.37 +/- 4.59; F = 5.93; p = 0.003), and less satisfied with the possibilities for postgraduate training than surgeons (5.27 +/- 1.90 vs. 6.59 +/- 2.07; F = 9.26; p < 0.001). Global job satisfaction was rather low but does not differ between the three medical groups. Disparities were observed in some segments (opportunity for further training and academic advancement, vacation, and salary). The reason for the family physician's relative satisfaction may be due to stable working conditions, independence in organizing work schedules and personal responsibility.

The aim was to establish the prevalence of succinylcholine use among Croatian anesthesiologists in adult elective and emergency surgery, as well as in pediatric surgery, regarding gender, position, working place, and working experience of physicians. The anesthesiologists were expected to express their personal opinions regarding the drug, as well as experienced side effects in their own clinical practice. A total of 125 anesthesiologists (out of 590 in Croatia) from both university and county hospitals in Croatia anonymously filled out the questionnaire regarding the use of succinylcholine (Appendix 1). The questionnaire was structured to assess the use of succinylcholine in adult elective and emergency surgery, and in pediatric anesthesia, to obtain the reasons for the preference or rejection of succinylcholine, and information about observed side effects. The differences in use regarding gender, position, working place, and working experience were tested using chi-squared test and Fisher's exact test. p < 0.05 was considered significant. Vast majority (approximately 70%) of anesthesiologists in Croatia still use succinylcholine. The percentages of anesthesiologists that never use succinylcholine in adult elective, adult emergency and pediatric surgery were 20%, 6%, and 31%, respectively. There were no significant differences in the use of succinylcholine regarding position, working place, and working experience, but male anesthesiologists used it less frequently in pediatric anesthesia compared with their female colleagues (chi2 = 5.08; p = 0.02). Forty-two per cent never experienced a complication from the drug use. The most frequently reported side effects were bradycardias (67%) and myalgias (54%), followed by prolonged blockade (33%), and allergy (33%). Asystole was reported by 10% of the respondents. In conclusion, succinylcholine is still widely used by anesthesiologists in Croatia. The majority of surveyed physicians were aware of its possible dangerous adverse effects, but still use it in certain situations. Therefore, indications and contraindications for its use deserve expert consensus guidelines based on the available scientific evidence.

Background and Objective: The profession of anaesthesiologist is demanding and potentially hazardous. Extended work shifts combined with intensive work load may adversely affect physicians' performance. The aim of this study was to explore the impact of a single in-hospital 24 h shift on the cognitive and psychomotor performance of anaesthesiologists in a surgical emergency department., Methods: Following ethical and institutional approval, 11 staff anaesthesiologists [six men, five women, age 48 (35-50), years of experience 17 (7-20), median (range)] successfully completed the study protocol. Four computer-generated psychological tests (CRD, Complex Reactionmeter Drenovac, Croatia) consisting of light signal position discrimination (CRD 311), simple visual orientation (CRD 21), simple arithmetic operations (CRD 11), and complex psychomotor coordination (CRD 411) were used to measure objective parameters of cognitive and psychomotor performance at four time points (D1 = 8:00 a.m., D2 = 3:00 p.m., D3 = 11:00 p.m.; and D4 = 7:00-8:00 a.m. next day) during the 24 h working day. The control testing on an ordinary working day was performed at two time points (C1 = 8:00 a.m., C2 = 3:00 p.m.). Three parameters were recorded: total test solving time (TTST), total variability, and total number of errors for all four tests., Results: TTST was significantly impaired during the 24 h shift in all tests, and TTST was prolonged in CRD 21 test at different time points from 1.6 +/- 1.4 to 5.5 +/- 1.6 s compared with the control (F = 6.39, P = 0.001). The reaction times were prolonged from 1.3 +/- 1.8 to 5.4 +/- 1.2 s (F = 3.49, P = 0.009) in CRD 311, from 3.8 +/- 9.0 to 34.3 +/- 5.8 s (F = 5.05, P = 0.002) in CRD 11 TTST, and from 0.8 +/- 3.0 to 16.3 +/- 8.6 s (F = 2.67, P = 0.034) in CRD 411. Total variability was significantly altered during the 24 h shift only in CRD 411 (F = 2.63, P = 0.036). There was no difference in the total number of errors between the 24 h shift and the ordinary working day., Conclusion: Anaesthesiologists' 24 h working day in the emergency department altered cognitive and psychomotor function in comparison with ordinary working days. Speed, reliability and mental endurance (measured by TTST) were significantly impaired in all four tests. Stability and reaction time (measured by total variability) were only slightly impaired. Paradoxically, attention and alertness (measured by total number of errors) were not adversely affected. In conclusion, anaesthesiologists' psychomotor performance was impaired during the single 24 h shift.

Background/introduction: Hyperbaric oxygenation (HBO) has been accepted in many countries as a method of treatment in selected indications, but in Croatia it is still perceived with skepticism., Objective: To determine beliefs, knowledge, and possible experience of Croatian surgeons and internists with HBO., Subjects and Methods: An anonymous questionnaire was applied to test surgeons (N=56; 45%) and internists (N=68; 55%), employed in general hospitals in Zadar, Sibenik, Split, and Dubrovnik, Republic of Croatia. We believed that the subjects had been previously exposed to information campaigns about HBO and its clinical applications, and should have been informed about the method at a level enabling correct establishment of indications and routine usage of HBO in clinical practice., Results: The majority of study subjects (N=66; 53%) had very little or no information at all about HBO and half of them (N=50; 40%) had no experience in its application. Almost all (N=123; 99%) subjects considered the method valuable in the treatment of decompression sickness, 56 subjects (45%) considered the method efficient in carbon monoxide poisoning, 31 (25%) in cerebral arterial gas embolism, 87 (70%) in problem wounds, and 70 (56%) in gas gangrene. The only statistically significant difference between the two groups of subjects was recorded in case of cerebral arterial gas embolism (chi2 = 7.26, P = 0.007), which was recognized as an indication for HBO by more internists (N=23) than surgeons (N=8)., Discussion: Insufficient understanding of HBO amongst Croatian surgeons and internists is probably the consequence of several factors, of which most important probably are insufficient curricula of undergraduate studies and residencies, as well as administrative obstacles. A small number of responders and polled hospitals necessarily resulted in a significant bias, so additional studies are necessary to shed more light on the issue.

Background: Although the paradigm of modern medicine is evidence-based practice, there is a lack of research output and interest in research in family medicine. We investigated attitudes towards scientific research among family medicine practitioners in a country in post-communist socioeconomic transition, and related it to their attitudes towards alternative medicine and clinical knowledge relevant for their practice., Methods: We surveyed 427 family medicine practitioners in Croatia about their attitudes towards scientific research (5-point rating scale, total score range 20-100) and alternative medicine (5-point rating scale, total score range 14-70). We also tested their knowledge on diagnosis and treatment of hypertension (10 questions) and diabetes (12 questions)., Results: The attitude towards scientific research was positive (score 79.0 +/- 7.2 out of maximum 100) and significantly more positive than that towards alternative medicine (score 45.0 +/- 9.9 out of maximum 70; t(425) = 19.06, P < 0.001). The respondents correctly answered about half the questions on hypertension and diabetes; knowledge on new diagnostic and treatment guidelines was better than their textbook knowledge. The attitude scores were not related to knowledge or research activity or the medical practice of the respondents., Conclusions: Family medicine practitioners in a transition country have a more positive attitude towards science than towards alternative medicine, despite the adverse situation in which they practice. To involve family medicine practitioners in research, interventions must be directed towards changes in behavior and practice and not only towards increasing positive attitudes.

Objectives: Our study aimed to assess differences in the susceptibility to severe acute illness in children with and without chronic health conditions treated in a pediatric intensive care unit (PICU)., Patients and Methods: Data on age, gender, need for ventilator support, length of stay, as well as other parameters for the Paediatric Index of Mortality (PIM2) score were collected. Data were analyzed and compared across three patient groups: those with a neurodevelopmental disability, those with a chronic condition other than a neurodevelopmental disability, and those with no chronic condition. Reasons for admission of patients were classified according to the Australia and New Zealand Paediatric Intensive Care Registry (ANZPIC Registry) diagnostic codes. In the multidisciplinary, seven-bed, level I PICU of the Split University Hospital, the admission data were collected prospectively for 591 consecutively admitted patients aged

Aim: To assess attitudes of students at the Split University Schools of Medicine, Economics and Business, and Electrical Engineering towards science and alternative medicine., Methods: There were 275 respondents surveyed for their opinion on science and different aspects of alternative medicine. The respondents were grouped into three major groups: medical students (83 or 30%), economics and business students (95 or 35%), and electrical engineering students (97 or 35%). Each group was composed of two subgroups: first and final year students. We used a specially designed questionnaire composed of four parts to collect students' demographic data and investigate their scientific experience and attitudes towards science and alternative medicine. ANOVA was used to test the differences among the three major groups of students and between first and final year students within each group., Results: There was no significant difference among the first year students at three different schools in their scores on attitude towards science (ANOVA; F=0.001, p=0.99) and the attitude towards alternative medicine (F=2.61, p=0.08). However, there was a significant difference among the final year students at the three schools, with medical students being the most positive in their score on the attitude towards science (F=7.30, p=0.001) and least positive in their score on the attitude towards alternative medicine (F=30.7, p<0.001). There was a negative correlation between attitudes towards science and alternative medicine (r=-0.37, p<0.001) for all schools., Conclusion: Medical students showed the most positive attitude towards science and least positive attitude towards alternative medicine, compared with the students of economics and business or electrical engineering. The curriculum of the Medical School, unlike the curricula of other two schools, could have an impact on students' attitudes towards science.

Aim: To assess the knowledge and attitudes regarding sleep medicine among second-year medical students and physicians., Methods: A total of 112 respondents were surveyed for their attitude and knowledge regarding sleep medicine and hypertension. The respondents were divided into three groups: 1) second-year medical students (46 or 41%); 2) physicians at postgraduate study program (26 or 23%); and 3) specialists in different fields (40 or 36%). The questionnaire was composed of the sleep medicine attitude test, sleep medicine knowledge test, and hypertension knowledge test. Differences among the groups were statistically analyzed with ANOVA, and differences within each group were analyzed with Wilcoxon test., Results: Postgraduate students and specialists showed better knowledge in hypertension than in sleep medicine (p=0.001 and p<0.001, respectively). In the student group, no difference was found between the knowledge in hypertension and sleep medicine (p=0.192). Differences in sleep medicine knowledge were not found between medical students and specialists (p=0.228) or between postgraduates and specialists (p=0.647). Sleep medicine attitude score was similar in all groups (p=0.470). In general, there was a positive correlation between sleep medicine knowledge and attitude (p=0.002), and between hypertension knowledge and sleep medicine attitude (p=0.019)., Conclusion: Medical students, postgraduate physicians, and specialists showed poor knowledge but positive attitude toward sleep medicine. This finding points to the need for better education in the field of sleep medicine in medical schools.
