Since vaccination coverage in Serbia has been decreasing and health professionals have been identified as the most important factor in making decisions about immunization, vaccination knowledge and attitudes of students, especially medical students, are of particular interest. A cross-sectional survey was carried out on three groups of 509 Belgrade University students (medical, law and engineering students). The data were collected using an on-line questionnaire posted to student groups and included the Vaccine Knowledge Questionnaire and Attitudes Toward Vaccination Scale. This survey also included questions about demographic characteristics and perceived negative experiences. Multiple linear regression analysis was performed. There was a significant difference in the Vaccine Knowledge score (F=40.48, p<0.01) among the three groups of students. Medical students (N=251, Mean=4.47, SD=1.71) had significantly higher mean knowledge scores than did law (N=128, Mean=2.80, SD=1.56) or engineering students (N=130, Mean=3.98, SD=1.81). Compared with the law (Mean=49.77, SD=10.23) and engineering students (Mean=57.62, SD=12.21), medical students (Mean=59.52, SD=9.62) also had significantly higher attitude scores (F=37.56, p<0.01). These findings demonstrate general positive attitudes of Serbian students toward immunization. However, some knowledge gaps were identified. Multivariate analysis showed that those who had better vaccine knowledge, those who studies medicine, those who attended at university for more years, and those who do not know someone who had a negative experience with vaccines were more likely to have positive attitudes toward vaccination. Considering the growing vaccination hesitance in the general population, this is an important result that indicates that medical students are possible important participants in future public health campaigns. A strong association between vaccine knowledge and attitudes implies recommendations to introduce a specialized vaccination curriculum at both the undergraduate and graduate levels of medical study.

Fragile X syndrome (FXS) is a global neurodevelopmental disorder caused by the expansion of CGG trinucleotide repeats (≥200) in the Fragile X Messenger Ribonucleoprotein 1 (FMR1) gene. FXS is the hallmark of Fragile X-associated disorders (FXD) and the most common monogenic cause of inherited intellectual disability and autism spectrum disorder. There are several animal models used to study FXS. In the FXS model of Drosophila, the only ortholog of FMR1, dfmr1, is mutated so that its protein is missing. This model has several relevant phenotypes, including defects in the circadian output pathway, sleep problems, memory deficits in the conditioned courtship and olfactory conditioning paradigms, deficits in social interaction, and deficits in neuronal development. In addition to FXS, a model of another FXD, Fragile X-associated tremor/ataxia syndrome (FXTAS), has also been established in Drosophila. This review summarizes many years of research on FXD in Drosophila models.

Background: Recently, it was established that more religious people tend to have less favorable views of vaccination. The aim of this study was to assess the relationship between the religiousness and attitudes towards COVID-19 vaccination and disease, in five Western Balkans countries. Methods: Using online questionnaire and convenience sampling procedure, data were obtained from 1605 respondents aged 18-75 years. Perceived COVID-19 vaccine safety and efficacy, and observed danger and susceptibility to disease were assessed by short five-point Likert scales. Religiousness was estimated using single item scale. Multivariate regression analysis was employed. Results: In Serbia, respondents who assessed themselves as more religious considered vaccine against COVID-19 as less safe (β=-.10, p<.01) and effective (β=-.12, p<.01), were more prone to the attitude that dangers of COVID-19 are not that serious (β=-.09, p<.01), and believed to a greater extent that they are less susceptible to the virus (β=-.07, p<.01). Similarly, in Bosnia and Herzegovina more religious individuals were less convinced that vaccine is effective (β=-.07, p<.05), less inclined to believe that danger of the virus is serious (β=-.07, p<.05), and assessed their susceptibility as lower (β=-.06, p<.05). More religious people in Montenegro (β=-.06, p<.05) regarded the vaccine as less safe, while in North Macedonia (β=.06, p<.05) and Albania (β=.08, p<.01) stronger religiosity was associated with more favorable attitudes towards vaccine safety. Conclusions: The relationship between religiosity and attitudes towards COVID-19 vaccination and disease is culturally conditioned. While in some Western Balkans societies religious beliefs render individual with a sense of lack of control triggering worry and anxiety, in some others they work as psychological shield against existential threats. Key messages: • Religiosity should be considered as a relevant factor in vaccination campaigns implementation. • In the societies where negative attitudes towards vaccination prevail among the believers, religious leaders should be peculiarly educated and encouraged to participate in vaccination campaigns.

Summary: Psychological distress in university students represents a rising public health concern. The complexity of this phenomenon calls for a more in-depth scrutiny, in order to address the wide diversity of mental health issues that may arise in this population. The instrument designed for the purpose of measuring the student-specific distress is needed. An appropriate tool is the Counseling Center Assessment of Psychological Symptoms 62 (CCAPS-62), multidimensional scale widely used at many universities. The objective of the present study was to translate, culturally adapt and psychometrically validate CCAPS-62 in Serbian student population. A total of 1326 Belgrade University students were recruited from twelve different faculties. Considering the possible culturally conditioned differences in the quality of distress both exploratory and confirmatory factor analyses were performed. The results of the exploratory factor analysis supported the eight-factor model with the item composition of the factors different to a certain extent from the original version. This measurement model was verified by confirmatory factor analysis. Findings demonstrated good internal consistency for the total scale as well as for the eight subscales applied among Serbian students. Implications are discussed with respect to the cultural context of mental health concerns in student population.
