Objectives: During the covid-19 pandemic, protective equipment such as respirators and masks were widely used to protect respiratory tract. This disposable protective equipment is usually made from plastic fibre-based nonwoven fabrics. If used masks and respirators are improperly discarded, they pollute the environment by becoming a source of micro and nanoplastics. The aim of the study was to find out how stable the materials of protective equipment are and how released nano and microplastics can affect aquatic and soil organisms.

Materials: The input materials used to produce respirators and masks were tested for their thermal stability and resistance to the release of plastic particles into the environment. To determine the thermal stability of the materials, a simultaneous thermal analysis - thermogravimetry (TGA) and differential scanning calorimetry (DSC) were performed.

Results: Materials of masks and respirators are stable at temperatures common to temperate climate zone. However, the possible effects of chemical reactions of the materials with the environment were not considered during the measurement. The materials were also subjected to ecotoxicity tests according to European standards.

Conclusion: While the leachate obtained by shaking the materials in water did not show acute toxicity to the selected aquatic organisms, the material itself had a significant effect on selected soil organisms (springtails).

Objectives: The aim of the study was the evaluation of the rs1107946 polymorphism of the COLIA1 gene impact on bone mineral density and fracture risk in Slovak postmenopausal women.

Methods: One hundred and twenty-seven postmenopausal Slovak women with a diagnosis of osteopenia/osteoporosis were genotyped for rs1107946 polymorphism of the COLIA1 gene. Clinical and anthropometric data were obtained. DNA isolation was performed using a standard protocol. Genetic analyses of the rs1107946 polymorphism of the COLIA1 gene were performed by the TaqMan SNP genotyping assays.

Results: The study confirmed a statistically significant relationship using an association analysis between the rs1107946 polymorphism of the COLIA1 gene genotypes and body weight of the Slovak postmenopausal women with osteopenia/osteoporosis (p = 0.03). The study revealed a significant association of the risk T allele of the rs1107946 polymorphism of the COLIA1 gene with osteoporotic fractures (p = 0.038). The odds ratio confirmed 2.060 times higher risk of osteoporotic fractures in Slovak postmenopausal women with the presence of risk T allele of the rs1107946 COLIA1 gene polymorphism (OR = 2.060; 95% CI: 1.024-4.144).

Conclusion: The results of this study revealed an association of T allele of the rs1107946 COLIA1 gene polymorphism with osteoporotic fractures in Slovak postmenopausal women with osteopenia/osteoporosis and suggest that the rs1107946 polymorphism of the COLIA1 gene may be a molecular biomarker usable in the management of osteoporosis.

Objectives: For the last three decades, although colorectal cancer incidence has been decreasing in those over 50 years of age, it has been increasing in those under 50 included in the pre-screening group (PSG). The present study aims to explain the screening-related factors and compliance of individuals in PSG who are not included in the colorectal cancer screening programme.

Methods: This cross-sectional study was conducted with a total of 323 participants, 143 of whom were from the pre-screening group (40-49 years), and 180 from the screening included group (SIG) (50-70 years).

Results: Individuals included in PSG were more likely to have accepted that both faecal occult blood test (FOBT) (2.23 ± 1.22 vs. 1.89 ± 1.33, p = 0.018) and colonoscopy (2.37 ± 0.97 vs. 2.02 ± 1.14, p = 0.003) were useful and suitable screening tests in colorectal cancer. Adequate health literacy (OR = 4.3, 95% CI: 1.8-10.0, p = 0.001) and better education level (OR = 3.3, 95% CI: 1.3-8.4, p = 0.010) were factors of increased knowledge of colorectal cancer screening.

Conclusions: The findings show that PSG has different characteristics than SIG and may be more fitting in the colorectal cancer screening programme if included.

Objectives: The aim of the study was to evaluate the immune status of young people from the Vojvodina province, Serbia, through the detection of IgG antibodies specific for the L1 protein of HPV types 6, 11, 16, and 18 contained in quadrivalent vaccine.

Methods: The study enrolled 514 healthy persons of both genders, aged between 18 and 30 years. All potential participants were informed about the project's aims by trained interviewers before venous blood collection. Also, participants completed a specially designed anonymous questionnaire to identify socio-demographic characteristics and individual behaviours associated with HPV seroprevalence. VPL HPV L1-specific IgG antibodies were measured using a semi-quantitative HPV IgG ELISA kit (Dia.Pro, Italy).

Results: A total of 472 (91.8%) young subjects had no detectable antibodies against high- and low-risk HPV types covered by the quadrivalent vaccine. A slightly higher number of seropositive individuals were detected in the age group of 26-30 years compared to younger than 25. Multivariate analysis showed that the number of lifetime sexual partners was the most powerful predictor of HPV seropositivity (OR = 3.483, 95% CI: 1.294-9.379).

Conclusions: Obtained data point out low levels of naturally induced HPV-specific serum antibodies among the target population in the Vojvodina province. The present work highlights the significance and potential benefits of HPV vaccination. Routine HPV vaccination should be the public health priority in our country and should be included in the national immunization programme as soon as possible.

Objectives: In Czech children, the burden related to the high body-mass index is rising. In the last three decades, Western eating patterns have influenced Czech children's diet, including the high consumption of sugar-sweetened beverages. This narrative review aims to evaluate evidence of the trend of sugar-sweetened beverages consumption in Czech children and its impact on the prevalence of childhood abnormal adiposity.

Methods: A comprehensive literature review in MEDLINE (PubMed) and a hand search using references in identified articles were performed. The inclusion criteria were population-based studies of randomly selected samples of children from 0 to 18 years old, data involving the Czech population, published from 1990 to 2021. The results were organized into three sections - childhood abnormal adiposity, SSBs consumption, and the association between SSBs consumption and abnormal adiposity.

Results: The studies showed a significant increase in abnormal adiposity in both genders and all age categories. The highest prevalence of abnormal adiposity was observed in boys and younger children. On the contrary, sugar-sweetened beverages showed a significant decline in daily consumption among Czech children of both genders and all age categories. No results were found for consequences of abnormal adiposity concerning sugar-sweetened beverages consumption.

Conclusion: Findings from this review could serve public health experts to detect the areas of a gap in research and establish potential interventions in vulnerable groups. Observation of potential obesogenic contributors - including sugar-sweetened beverages - should be an integral part of effective action against the obesity pandemic.

Objectives: Although clinical research is still going on to determine any relationship between vitamin D and sleep regulation, only few studies have identified the role of vitamin D metabolism in sleep disorders. The current study aims to examine the incidence of vitamin D deficiency/insufficiency in the sample group and its effects on sleep quality and melatonin level.

Methods: A cross-sectional study was designed. A total of 79 women aged 18-49 years who applied to the research and training hospital between 1 October and 30 November 2021 participated in the study. Data were collected using a socio-demographic questionnaire prepared by the authors and the Pittsburgh Sleep Quality Index (PSQI). Blood samples were taken from the participants, also, 25-OH-vitamin D3 and melatonin levels in serum samples were measured by ELISA.

Results: The participants (n = 79) were aged 29.61 ± 11.14 years. The mean total PSQI scores of the participants were calculated as 5.77 ± 2.70. We determined that 64.6% of the participants had vitamin D deficiency, 21.5% had vitamin D insufficiency, and 13.9% of the participants were vitamin D sufficient. The mean melatonin level was found to be 24.77 ± 27.77 ng/L. We determined that an increase in the melatonin levels decreases the risk of vitamin D deficiency. Besides, our findings showed a good positive correlation between serum melatonin and 25 OH vitamin D3 levels (r = 0.544, p < 0.001).

Conclusion: Our results indicate that the correction of vitamin D insufficiency can positively affect melatonin levels, therefore, it may positively contribute to the treatment of sleep disorders related to melatonin deficiency.

Objectives: In 2020, measures against the spread of COVID-19 were adopted, including nationwide school closures, restrictions on the free movement of persons and leisure time sports activities. The aim was to assess the impact of COVID-19-associated restrictions on the performance of paediatric and adolescent competitive athletes by comparing basic anthropometric and performance parameters.

Methods: The sample comprised 389 participants (115 girls, 274 boys). All participants were examined during regular preventive sports health checks from September to November 2019 and a year later. At the initial examination, the mean age of the entire sample was 12.2 ± 2.7 years (median 12.0, minimum 7.0; maximum 17.0). The examination consisted of a complete medical history and physical examination including maximal exercise testing on a leg cycle ergometer.

Results: In the entire sample, as well as in the boy and girl subgroups, body height, weight, body mass index (BMI), BMI percentile, and power output significantly increased according to a percentile graph for boys and girls in 2020. A reduction in power output (W/kg) was found. By 2020, W/kg dropped in 56.4% of the youngest participants (7-13 years), 75% of those aged 14-16 years and 64.9% of the oldest individuals (16-17 years). The percentage of the youngest children with power output reductions was statistically significantly lower than the percentages of the other age subgroups (p = 0.007). There were no significant differences in results between genders.

Conclusions: Performance and anthropometric parameters worsened especially among older children. This should be reflected when planning epidemic measures in case of any similar situation in the future.

Objectives: Indoor air toxicity is of major public health concern due to the increase in humidity-induced indoor mould exposure and associated health changes. The objective is to present evidence for the causality of health threats and indoor mould exposure.

Methods: PubMed search on the following keywords: dampness, mould, indoor air quality, public health, dampness, and mould hypersensitivity syndrome, sick building syndrome, and building-related illness as well as information from the health authorities of Bavaria and North Rhine-Westphalia, the Center of Disease Control (CDC), World Health Organisation (WHO), and guidelines of professional societies.

Results: The guidelines of professional societies published in 2017 are decisive for the assessment of the impact of mould pollution caused by moisture damage on human health and for official regulations in Germany. Until 2017, a causal connection between moisture damage and mould exposure could usually only be established for pulmonary diseases. The health risk of fungal components is apparent as documented in the fungal priority pathogens list (FPPL) of the WHO. Since 2017, studies, especially in Scandinavia, have proved causality between moisture and mould exposure not only for pulmonary diseases but also for extrapulmonary diseases and symptoms. This was made possible by new test methods for determining the toxicity of fungal components in indoor air. Environmental medical syndromes, e.g., dampness and mould hypersensitivity syndrome (DMHS), sick building syndrome (SBS), building-related symptoms (BRS), and building-related illness (BRI), and fungal pathogens, e.g., Aspergillus fumigatus, pose a major threat to public health.

Conclusion: There is evidence for the causality of moisture-induced indoor moulds and severe health threats in these buildings. According to these findings, it is no longer justifiable to ignore or trivialize the mould contamination induced by moisture damage and its effects on pulmonary and extrapulmonary diseases. The health and economic implications of these attitudes are clear.

Objective: Extrapulmonary tuberculosis (EPTB) in children globally represents a proportion of all cases of tuberculosis, reaching 20% according to published reports. Children are at a higher risk for disseminated TB and extrapulmonary forms. The most prevalent clinical presentations of EPTB in children worldwide are peripheral lymphadenitis and osteoarticular TB. Peritoneal, urogenital, or meningeal tuberculosis is less frequent, and their diagnosis is often difficult. The aim of the study was the determination of EPTB incidence in children in a low-prevalence region over 35 years.

Methods: Descriptive retrospective study of the incidence of EPTB in children and adolescents (aged 0-18 years) in the Czech Republic in the years 1987-2021 as reported in the tuberculosis register.

Results: Total amount of EPTB cases was 95. The most prevalent form was extrathoracic lymph node TB. The median age was 10 years. Most patients (84%) were Czechs. None of them died. The ratio of pulmonary and extrapulmonary TB was 79.8% to 20.2%.

Conclusion: The low incidence of EPTB in Czech children is congruent with a low incidence of TB in the Czech Republic. Our study confirms that the most frequent form of EPTB is peripheral lymph node TB. Our study did not prove a significant change in the trend of EPTB after the cessation of the mandatory Bacillus Calmette-Guerin (BCG) vaccination programme.
