Despite world-level efforts and the endeavors of scientists and medical professionals in suppressing the COVID-19 pandemic, inadequate levels of vaccine literacy of the general population can represent a grave obstacle. The aim of this study was to evaluate COVID-19 vaccine literacy in the Croatian adult general population before vaccination began. The specific objectives were to test differences regarding socio-demographic characteristics and to examine perceptions and attitudes about vaccination against COVID-19 considering the level of VL against COVID-19. A cross-sectional study with a translated and psychometrically tested questionnaire was conducted in 1227 participants before the start of vaccination, from 15 to 31 January 2021. The results show a medium level of vaccine literacy (M = 2.37, SD = 0.54) and a significant difference between functional and interactive-critical vaccine literacy (p < 0.001). The level of vaccine literacy grew with the level of education (p = 0.031) and reduced with age (p < 0.001). Participants who were employed, had chronic diseases, took medicine, or consumed alcohol daily had a lower level of vaccine literacy. There is room for progress in the COVID-19 VL level for the adult population in Croatia, especially at the interactive-critical VL, which could have an important role in people accepting the vaccine against the COVID-19 disease. A satisfactory level of vaccine literacy in the population is necessary because it can contribute to the fight against the pandemic.

The aim of this study was to examine the levels of health-related quality of life (HRQoL), pain intensity, and mental distress in participants with chronic low back pain (CLBP), and to examine the differences in the HRQoL of participants with respect to mental distress and the correlations of the examined variables. Data were collected from 148 patients using the SF-36 Health Status Questionnaire (SF-36), the Clinical Outcomes in Routine Evaluation–Outcome Measure (CORE-OM) questionnaire, and the visual-analog pain scale (VAS). The results indicate poorer self-assessment of physical health (M_e = 28.1) compared to mental health (M_e = 39.4). Participants with higher levels of mental distress reported significant emotional limitations (p = 0.003), lower energy (p < 0.001), poorer psychological health (p < 0.001) and social functioning (p < 0.001), more pain (p = 0.007), and, ultimately, poorer general health (p < 0.001). The level of mental distress was related to the level of HRQoL, while a correlation with the level of pain of the participants was not found. The study results indicate a connection between the presence of mental distress and almost all aspects of HRQoL in participants with CLBP.

The process of population ageing with socioeconomic and political implications necessitates the creation of sustainable social strategies aimed at societal inclusion, support of subjective well-being and successful ageing of older adults. Therefore, the aim of this cross-sectional study was to explore individual and contextual factors and predictors which impede the possibility of successful ageing. The study was conducted from January to June 2024 through a questionnaire involving 403 elderly participants who live in the Eastern region of Croatia—Slavonia. The Diener Scale of Subjective Well-being and Self-assessment of Successful Ageing Scale were used in this research. A separate and model contribution of predictors (gender, age, subjective age, residence, level of education, marital status, comorbidities, Satisfaction with Life Scale and Prosperity Scale) were examined using bivariate and multivariate regression. Multivariate regression differentiated a statistically significant model, which as a whole explains between 41% and 55% of the variance of the present negative assessment of successful ageing, correctly classifying 80% of cases. The significant predictors included subjective age, place of residence, level of education, comorbidities, Satisfaction with Life Scale, and Prosperity Scale. These findings underscore the importance of both individual and contextual factors in successful ageing within this specific regional context.

This prospective study aimed to determine the cognitive and emotional status among patients with chronic pain and to examine the potential influence on the treatment success, measured by the reduction in pain intensity and adherence to pharmacotherapy. A total of seventy patients were followed for two months. The results of the comparison between patients who did and did not follow the physician’s instructions regarding adherence to pharmacotherapy showed a significant difference in cognitive status and a reduction in pain intensity. Patients who followed the physician’s instructions on taking analgesics had significantly higher scores on the Montreal Cognitive Assessment (MoCA) of cognitive status and a substantially higher reduction in pain intensity. Scores on the MoCA test provide statistically significant indications regarding patients’ decision to follow instructions regarding adherence to pharmacotherapy. Scores on the MoCA test, anxiety, age, and pain intensity (measured with a numeric rating scale—NRS) on admission were identified as potential predictors for the reduction in pain intensity. The linear regression model was statistically significant (χ² = 40.0, p < 0.001), explained between 43.5% and 61.1% of variance regarding the reduction in pain intensity. The findings of this study show that cognitive status, measured with MoCA, and emotional status, measured with the Depression, Anxiety, and Stress Scale (DASS-21), significantly influence the reduction in pain intensity and adherence to pharmacotherapy. The results suggest that cognitive and emotional status may be potential predictors of treatment success. This finding points to the importance of a biopsychosocial approach in the treatment of chronic pain, where an important emphasis can be placed on the psychosocial determinants of pain.

Background: Colorectal cancer (CRC), one of the leading public health problems worldwide, is a disease that can be prevented when it is detected in time. The objectives of this cross-sectional study were to investigate the characteristics of colorectal adenomas and whether alcohol consumption and cigarette smoking correlated with the development of advanced adenomas in participants in The National Programme for Early Detection of Colorectal Cancer (NP) in Osijek-Baranja County (OBC), Croatia. Methods: The screening methods were the guaiac Faecal Occult Blood Test (gFOBT), colonoscopy, histological analysis, and risk factor questionnaire. Results: The results showed the presence of adenomas in 136 men (57.4%) and 101 women (42.6%), p < 0.001. There was one adenoma in 147 (62%) most commonly located in sigmorect, in 86 (59%) participants, and 44 (18.6%) participants had multiple adenomas, most commonly found in multi loc, p < 0.001. According to size, 118 (49.8%) of all adenomas were between 0.1 and 0.9 cm, while adenomas of 3 cm 19 (8%) were the fewest, p < 0.001. There were 142 (59.9%) advanced adenomas. Conclusions: Adenoma development in the OBC population was correlated with predictors: adenoma size, high-grade dysplasia, smoking and alcohol consumption of 20 g per day. Non-smoking was found to be a health protective behaviour.

Background: Aging is a multidimensional process influenced by biological, psychological, and social factors. Social support contributes to cognitive reserve by reducing stress, promoting mental engagement, and reinforcing a sense of belonging. Objective: To examine the association between perceived social support and cognitive functioning among older adults, and to investigate whether social support mediates the relationship between living arrangements and cognitive performance. Methods: The sample included 265 older adults aged 65 years and above, recruited using snowball sampling between March and July 2025 in rural communities. Instruments included the Montreal Cognitive Assessment for cognitive function and the Multidimensional Scale of Perceived Social Support for social support. Results: In this study, higher perceived social support from family, friends, and significant others was associated with better cognitive performance. Multiple regression showed that all three dimensions of social support significantly predicted MoCA scores, with the strongest effect from friends’ support. Mediation analysis revealed that perceived social support mediated the relationship between living arrangements and cognitive functioning, while the direct effect of cohabitation alone was not significant. Conclusions: These results highlight the importance of perceived social support in preserving cognitive health in older adults.
