The aim of this study was to assess the association between cigarette smoking and health-related quality of life (HRQoL) among students in two different universities, and the potential mediating effect of depression. Participants were students who came for mandatory check-ups at Student Health Care Centers in two Universities in Serbia, differing by socio-politically and economically environments. Students completed socio-demographic questionnaire, Beck Depression Inventory (BDI) and the SF-36 questionnaire for assessment of HRQoL. In both populations, after adjustment for socio-demographic, behavioral and health factors, smoking was associated with poorer Mental Composite Score (MCS) and Physical Composite Score (PCS) (Belgrade 1,624 students: MCS β = 3.38, 95% confidence interval [CI] 1.31, 5.44, PCS β = 1.01, 95% CI -0.50, 2.52; Kosovska Mitrovica 514 students: MCS β = 5.06, 95% CI 1.74, 8.37, PCS β = 3.29, 95% CI 0.75, 5.83). After additional adjustment for BDI score, the observed associations were lost (Belgrade: MCS β = 1.12, 95% CI -0.57, 2.80, PCS β = -0.40, 95% CI -1.71, 0.92; Kosovska Mitrovica: MCS β = 0.77, 95% CI -2.06, 3.60, PCS β = 0.56, 95% CI -1.75, 2.87). Higher BDI score was associated with poorer PCS and MCS across all quintiles. The association of smoking with impairment of HRQoL among university students in two different settings was mediated by higher levels of depressive symptoms. These findings highlight the need for further research on the interaction between smoking, mental health and quality of life, with implications for prevention, diagnosis and treatment.

Antibiotics are often misused, especially for the treatment of upper respiratory tract infections (URTIs) in children, where their use is unnecessary and leads to antimicrobial resistance. This study sought to explore the knowledge, attitudes and practices (KAP) of parents and pediatricians on the use of antibiotics among children and whether the level of education of parents has an impact on their KAP. The research was carried out among 1459 parents of children under 6 years of age and among 18 pediatricians. Sixty percent of pediatricians (61.1%) were prescribed antibiotics daily in their practice. Most of the surveyed parents (98.4%) state that doctors are their main source of information when deciding on the use of antibiotics in the treatment of their children. Parents with a higher level of education use television less often as a source of information when making this decision compared to parents with a lower level of education (p = 0.039, i.e., p = 0.003). The majority of parents (80.7%) knew that Panklav (amoxicillin/clavulanic acid) is an antibiotic, while 52.5% identified Pancef (cefixime) as an antibiotic. Parents with a higher level of education correctly identified antibiotics significantly more often (p < 0.001). This study shows that in the Republic of Srpska, parents have adequate knowledge about antibiotics, especially those with a higher level of education, who show better KAP when it comes to antibiotic use.

Although studies on HIV knowledge have previously been conducted in central Serbia and southern Kosovo, none has included the Serbian population residing in the northern part of the Kosovo province. The aim of this study was to assess HIV-related knowledge and to estimate factors contributing to a higher HIV-related knowledge level among Serbian university students in the Kosovo province. A cross-sectional study including 1017 first- and fourth-year students enrolled at the University of Pristina temporarily seated in Kosovska Mitrovica was carried out during the academic year 2013–2014. The students completed a 31-item questionnaire comprising demographic data, HIV transmission knowledge and attitude towards HIV testing. Data were statistically analysed. Students demonstrated good knowledge of HIV (average 32.8 ± 3.3 out of a maximum 42). Only 5% of the students reported having been tested for HIV. Factors associated with being more knowledgeable about HIV were studying health-related disciplines (β= −0.09; 95% confidence interval [CI] −0.13, 0.00), using the internet as a source of information about HIV (β= −1.09; 95% CI −1.65, −0.52), having a positive attitude towards HIV testing (β= −0.43; 95% CI −0.59, −0.26), having a low self-perceived risk for HIV infection (β= 0.41; 95% CI 0.23, 0.56) and the position that one would keep the same level of contact with an HIV-positive person after learning their HIV status (β= 0.38; 95% CI 0.21, 0.55). Setting up specialized classes on this topic at high schools and universities could help to increase the awareness of HIV infection and promote HIV testing and a positive attitude towards HIV-positive persons.

In December 2019, the virus SARS-CoV-2 responsible for the COVID-19 pandemic was detected in the Chinese city of Wuhan. The virus started to spread from China and dispersed over the rest of the world. In March 2020, WHO (World Health Organization) declared COVID-19 a pandemic. The transmission path of the pandemic was accelerated by different types of transportation. With complete analysis of spatial data, population density, types of traffic networks, and their properties, the spatial distribution of COVID-19 was estimated. GIS (Geographical Information System), numerical methods, and software for network analysis were used in this research to model scenarios of virus distribution on a global scale. The analyzed data included air, railway, marine, and road traffic. In the pandemic research, numerous models of possible trajectory of viruses can be created. Many have a stochastic character. This study includes all countries in the world affected by the COVID-19 up to date. In this study, GIS methods such as buffer, interpolations, and numerical analysis were used in order to estimate and visualize ongoing COVID-19 pandemic situation. According to the availability of new data, trajectory of virus paths was estimated. On the other hand, sparsely populated areas with poorly developed and small traffic networks (and isolated island territories) tend to be less or not affected as shown by the model. This low-cost approach can be used in order to define important measures that need to be addressed and implemented in order to successfully mitigate the implications of COVID-19 not only on global, but local and regional scales as well.

Objective: The study objective was to investigate factors associated with condom use among university students. Methods: During the 2013–2014 academic year, 1017 first and fourth year students from the University of Pristina temporarily seated in Kosovska Mitrovica, northern Kosovo, completed a questionnaire on sociodemographic data, HIV-related knowledge, attitudes and risky behaviours. Results: Condom use during the most recent sexual encounter and with casual partners was reported by just over half of participants. Factors associated with condom use during the most recent sexual encounter were: being male (35.1%), using medical sources of information about HIV (35.7%), having a positive approach to HIV testing (40.1%) and a positive attitude towards sex workers (17.7%), as well as not having had a sexually transmitted infection in the past year (54.2%). Factors associated with more frequent condom use with casual partners were: being single (28.9%), not living in a rented apartment or own home (32.1%), frequenting night clubs at the weekend (35.3%), not using drugs/opioids (54.1%), not being sure whether to keep a contact after learning of their HIV-positive status (10.1%), and having stronger opinions (either positive or negative) on homosexual individuals (15.5% and 32.1%, respectively), sex workers (18.7% and 23.9%, respectively) and drug users (13.2% and 36.5%, respectively). Conclusion: Condom use among students in northern Kosovo was low. Strategies for HIV prevention should be focussed on promoting healthy behaviours, especially among female students and students who live alone while at university. Moreover, sexuality education should be carried out in schools and primary health care centres to provide support and enable young people to negotiate safe sex.
