Visual presentation of a medical physiology seminar modifies dental students' perception of its clinical significance.

INTRODUCTION: The primary objective of this study was to assess whether exposing dental students to visual stimuli related to dental profession during the medical physiology seminar could affect their perception of the clinical relevance of the topic. SUBJECTS AND METHODS: A self-administered questionnaire on attitudes towards medical physiology was conducted amongst 105 students of the School of Dental Medicine in Zagreb, Croatia, aged 19-24 years (80% females) following a seminar on respiratory system physiology. Power-point presentation accompanying the seminar for a total of 52 students (study group) was enriched with pictures related to dental practice in order to assess whether these pictures could make the topic appear more clinically relevant for a future dentist. RESULTS: The results of the survey indicated that dental students in the study group perceived the topic of the seminar as more important for them as future dentists when compared to the perception of the control group (P = 0.025). DISCUSSION AND CONCLUSION: The results of this survey encourage physiology lecturers to present medical physiology as clinically relevant for dental students whenever possible as this could increase students' interest in the subject and their motivation for learning. Such an approach could be particularly beneficial if there is a significant time gap between basic courses and involvement of students into clinical training for it could promote meaningful learning.

The relationship between sleep habits and academic performance in dental students in Croatia.

INTRODUCTION: It is well accepted that sleep and lifestyle habits affect academic success in students. However, sleep patterns and sleep problems amongst dental students have been insufficiently addressed in the literature. The purpose of this study was to evaluate sleep habits of dental students and the relationship between sleep habits and academic performance. MATERIALS AND METHODS: A self-administered questionnaire on sleep habits, academic performance and lifestyle was administered. The participants were 447 dental students from Split University Dental Medicine School and Zagreb University Dental Medicine School from the six academic years. The subjects were classified into two groups based on academic success (high-performing vs. low-performing students) for comparison of sleep and lifestyle habits. RESULTS: Amongst the whole group of students, average bedtime and wake time during weekday was significantly earlier compared with weekend. Main findings indicate that students with high academic performance had earlier bedtimes during weekdays and weekends, earlier wake times during weekends and shorter sleep latency compared with low academic performing students. CONCLUSION: Self-reported academic performance of dental students in Croatia is associated with timing of sleep and wakefulness, rather than with total sleep time duration.

Depression in Croatian Type 2 diabetic patients: prevalence and risk factors. A Croatian survey from the European Depression in Diabetes (EDID) Research Consortium.

AIMS: To determine the prevalence rate of and risk factors for depression in Croatian Type 2 diabetic patients. METHODS: Depressive mood was examined in 384 randomly selected outpatients with Type 2 diabetes. Center for Epidemiological Studies Depression Scale (CES-D) and Structured Clinical Interview for DSM-IV Axis I Disorders (SCID) were used to identify depressive disturbances. The groups with CES-D > or = 16 and < 16 were compared with respect to demographic, psychological and clinical characteristics. Regression analysis was used to determine risk factors for depression. RESULTS: Of the examined patients, 22% had CES-D scores > or = 16, and in 33% of them clinical depression was confirmed by the psychiatric interview. Depressed patients compared with the non-depressed ones reported more diabetes-related problems and poorer well-being (t = 6.71, P < 0.001 and t = 11.98, P < 0.001, respectively). Multiple regression analysis indicated female gender, experienced support and the level of emotional well-being to predict depression (R = 0.74, F = 15.3, P < 0.001). CONCLUSIONS: The obtained data indicate that the prevalence rate in Croatian Type 2 diabetic patients is comparable to findings from other cultural settings. Depressive symptoms can be predicted by psychological rather than disease-related variables. Psychological care for diabetic patients may be necessary to prevent depressive symptomatology.
