BACKGROUND: Previous studies have shown that personality traits (i.e., openness to experience, conscientiousness, and agreeableness) relate to prejudicial attitudes. However, one of the aspects of prejudice is social distance; its association with personality traits was overlooked by previous studies. Therefore, this study examines the connection between the Big Five personality traits and social distance toward certain social groups. PARTICIPANTS AND PROCEDURE: Participants from the general population were recruited through leaflets, the institutional webpage, Facebook, and through the project recruitment website and assessed via paper-and-pencil or online form. A total of 214 participants were included (of whom 68.2% were women and the mean age was 32.65, SD = 11.27, range 18-72) who completed the Bogardus Social Distance Scale and the 44-item Big Five Inventory questionnaire. RESULTS: The results showed a relationship between social distance, agreeableness, and openness to experience. Agreeableness seems to lower the social distance toward all studied groups. In comparison, openness to experience seems to lower the social distance towards groups that evoke more polarized attitudes in the majority (e.g., migrants). Furthermore, the influence of demographic characteristics (i.e., age, education level, and gender) is also significant. CONCLUSIONS: This study shows that personality is significantly related to social distancing and expression of prejudicial attitudes. In particular, agreeableness and openness to experience have different effects on social distance and attitudes towards different groups. Further implications are discussed.

OBJECTIVES: Acute appendicitis is the most common non-gynaecological indication for surgical intervention during pregnancy. The aim of this study was to compare perioperative and postoperative results of surgical treatment of acute appendicitis in the early and late stage of pregnancy. MATERIAL AND METHODS: This is a retrospective study focused on the evaluation of perioperative and postoperative results of appendectomy in pregnancy. The study included all pregnant patients who underwent laparoscopic or open appendectomy at the University Hospital Ostrava during the observed 10-year period (January 2012-December 2021). The patients were divided into two subgroups according to the stage of pregnancy in relation to the expected viability of the foetus (the viability limit was defined as the 23rd week of pregnancy). RESULTS: In the monitored 10-year period, a total of 25 pregnant patients underwent appendectomy. Comparing the two subgroups of patients, there were no statistically significant differences in any of the admission parameters. Laparoscopy was performed in 100% of the patients in the lower stage of pregnancy (< 23 g.w.) and in 61% of the subgroup of patients with more advanced pregnancy (> 23 g.w.); this difference was statistically significant (p = 0.039). Differences in subgroups regarding duration of surgery, risk of revision and 30-day postoperative morbidity were not statistically significant. In the subgroup of patients < 23 g.w., uncomplicated forms of appendicitis predominated (66%), whereas in the subgroup > 23 g.w., complicated forms predominated (69%); this difference was statistically significant (p = 0.026). When comparing the two subgroups of patients, there was a statistically significant difference in the length of hospitalization (p = 0.006). The mortality rate of the group was zero. CONCLUSIONS: The results of the study confirm the fact that advanced pregnancy may be related to complicated forms of appendicitis. Therefore, early appendectomy is still the method of choice. In accordance with the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) recommendations, laparoscopic approach is preferred in pregnant patients, even in advanced pregnancy.

This study investigates the potential relationship between exposure to polycyclic aromatic hydrocarbons (PAHs), specifically monohydroxylated metabolites (OH-PAHs), in urine, and the prevalence of respiratory diseases in 2-year-old children residing in two locations within the Czech Republic - České Budějovice (control location) and the historically contaminated mining district of Most. Despite current air quality and lifestyle similarities between the two cities, our research aims to uncover potential long-term health effects, building upon previous data indicating distinctive patterns in the Most population. A total of 248 urine samples were analysed for the presence of 11 OH-PAHs. Employing liquid-liquid extraction with ethyl acetate and clean-up through dispersive solid-phase extraction, instrumental analysis was conducted using ultra-high performance liquid chromatography coupled with tandem mass spectrometry. The incidence of respiratory diseases was assessed through questionnaires administered by paediatricians. The concentrations of OH-PAHs were elevated in urine samples from 2-year-olds in Most compared to those from České Budějovice. The incidence of respiratory diseases showed statistically significant higher levels of OH-PAHs in children from Most, together with a higher incidence of influenza. This association underlines the impact of environmental PAH exposure on children's respiratory health. It suggests that elevated urinary OH-PAH levels indicate an increased risk of developing respiratory diseases in the affected population. Further studies are needed to clarify the possible long-term health effects and to contribute to sound public health strategies.

BACKGROUND: The current obstructive sleep apnea (OSA) diagnostic uses polysomnography or limited polygraphy and requires specialized personnel and technical equipment. Glycoprotein biomarkers and microRNAs are being explored as a possible new method for screening. We aimed to evaluate whether certain biomarkers and microRNA, previously identified as related to OSA, could be influenced by factors such as gender, age, and obesity level in patients with OSA. METHODS: In this retrospective analytical study, patients with moderate to severe OSA (n = 130) were compared with the control group. Serum levels of selected biomarkers and microRNA were taken from both groups. The group of OSA patients was then stratified by gender, obesity level, and age to see the possible influence of those variables on biomarker levels. RESULTS: Levels of all studied biomarkers - C-reactive protein (CRP), high-sensitivity troponin I (hsTnI), pentraxin-3 (PTX-3), and microRNA-499 were significantly higher in patients with OSA compared to the control group. In the OSA group only hsTnI showed a statistically significant relationship with gender. Levels of CRP and hsTnI showed a significant dependence on the level of obesity. Dependency on age was proven for hsTnI. CRP, PTX-3, and microRNA-499 did not have any statistically significant relationship with age. CONCLUSION: We found that serum levels of pentraxin-3 and microRNA-499 in patients with moderate to severe obstructive sleep apnoea are independent of gender, obesity, and age. CRP was affected by the level of obesity and hsTnI was influenced by all 3 variables. We consider these findings important for further research of OSA biomarkers.

The phenomenon of post-activation performance enhancement plays an unidentified role in movement eccentric speed and individual muscle group responses. Therefore, this study aimed to determine whether the loaded front squat (FSq) speed of the eccentric phase would influence the post-activation performance enhancement effect and whether the FSq would elicit similar performance enhancement of knee flexion, knee extension, hip flexion, and hip extension muscles. Twenty resistance-trained handball players performed the FSq under maximum eccentric-concentric speed and 2-s eccentric speed (only the eccentric phase performed), while pre- and post-front squat countermovement jump, knee, and hip isokinetic flexion/extension performance were tested. The FSq conditioning activity was performed in a single set of three repetitions with either 90% (maximum eccentric-concentric speed) or 120% (2-s eccentric speed) of one repetition maximum, and post-performance was measured 4-12 min after the FSq. Athletes randomly changed the FSq eccentric speed and tested the hip or knee isokinetic flexion/extension strength at 180°/s. ANOVA showed that the rate of force development during the jump increased (Cohen d = 0.59-0.77) with no differences between 2-s eccentric and maximum speed eccentric protocols. Isokinetic strength increased after the 2-s eccentric FSq in hip extension (d = 0.76-0.86), knee flexion (d = 0.74-0.88), and hip flexion (d = 0.82), with no differences in knee extension strength. After maximum eccentric-concentric speed, isokinetic strength increased in hip extension (d = 1.25). In conclusion, the FSq conditioning activity enhances hip extensors' performance more than knee extensors' performance. Different eccentric types of muscle action during a conditioning activity alter the level of local muscle enhancement.

400-m races are based on anaerobic energy metabolism, they induce significant muscle fatigue, muscle fiber damage, and high blood lactate (LA) concentration. Despite extensive research on sprint training, our understanding of the training process that leads to world-class sprint performance is rather limited. This study aimed to determine differences in LA concentration and anaerobic power using jumping tests after an intense glycolytic effort in a group of elite and sub-elite 400-m runners. One hundred thirty male runners were divided into two groups: elite (n = 66, body mass = 73.4 ± 7.8 kg, body height = 182.1 ± 6.2 cm, age = 20.8 ± 4.0 y) running the 400-m dash below 50 s and sub-elite (n = 64, body mass = 72.0 ± 7.1 kg, body height = 182.1 ± 5.2 cm, age = 20.8 ± 4.0 y) with a 400-m personal best above 50 s. The power of the countermovement and the sequential squat jumps was measured in two sets after a warm-up, followed by two intermittent 30-s Wingate tests. LA concentration was measured eight times. It was observed that elite athletes achieved significantly higher power in both types of jumps. The maximum post-exercise LA concentration was significantly lower in the sub-elite group after the 3rd, the 6th, the 9th, and the 20th min after the cessation of two Wingate tests (p < 0.001). The rate of LA accumulation after exercise and the rate of LA utilization did not differ between the groups. It can be concluded that elite and non-elite runners differ in higher LA production but not in LA utilization. Anaerobic power and LA concentration seem to differentiate between 400 elite and sub-elite performance.

Oxidative stress markers have a distinct role in the process of demyelination in multiple sclerosis. This study investigated the potential correlation of markers of oxidative stress (glutathione [GSH], catalase) with the number of demyelinating lesions and the degree of disability, cognitive deficit, and depression in patients with relapsing-remitting multiple sclerosis (RRMS). Sixty subjects meeting the criteria for RRMS (19 men and 41 women), and 66 healthy controls (24 men, 42 women) were included. In this study, GSH significantly negatively correlated with the degree of cognitive impairment. This is the first study of subjects with RRMS that performed the mentioned research of serum GSH levels on the degree of cognitive damage examined by the Montreal Scale of Cognitive Assessment (MoCA) test. The development of cognitive changes, verified by the MoCA test, was statistically significantly influenced by the positive number of magnetic resonance lesions, degree of depression, expanded disability status scale (EDSS), age, and GSH values. Based on these results, it can be concluded that it is necessary to monitor cognitive status early in RRMS patients, especially in those with a larger number of demyelinating lesions and a higher EDSS level and in older subjects. Also, the serum level of GSH is a potential biomarker of disease progression, which could be used more widely in RRMS.

<br><b>Introduction:</b> The early detection and diagnosis of dementia are of key importance in treatment, slowing disease progression, or suppressing symptoms. The possible role of changes in the sense of smell is considered with regard to potential markers for early detection of Alzheimer's disease (AD).</br> <br><b>Materials and methods:</b> A literature search was conducted using the electronic databases PubMed, Scopus, and Web of Science between May 30, 2022 and August 2, 2022. The term "dementia" was searched with keyword combinations related to olfaction.</br> <br><b>Results:</b> A total of 1,288 records were identified through the database search. Of these articles, 49 were ultimately included in the analysis. The results showed the potential role of changes in the sense of smell as potential biomarkers for early detection of AD. Multiple studies have shown that olfactory impairment may be observed in patients with AD, PD, MCI, or other types of dementia. Even though smell tests are able to detect olfactory loss caused by neurodegenerative diseases, they cannot reliably distinguish between certain diseases.</br> <br><b>Conclusions:</b> In individuals with cognitive impairment or neurodegenerative diseases, olfactory assessment has repeatedly been reported to be used for early diagnosis, but not for differential diagnosis.</br>.

INTRODUCTION: Patient satisfaction is an important indicator of the quality of care provided. Evaluating women's satisfaction with childbirth is essential to improving obstetric care and ensuring a positive experience for mothers and newborns. The tools used to measure women's satisfaction with childbirth are very heterogeneous and multidimensional. Assessment tools used in practice should be tested and meet characteristics that are consistently validated.The aim is to identify currently available instruments measuring women's satisfaction with childbirth and to evaluate their structure, content and psychometric properties. METHODS: A systematic search for sources was carried out according to the criteria set. For the included studies, psychometric properties were assessed in accordance with the principles of the guideline for completing systematic reviews of patient-reported outcome measures, COSMIN. RESULTS: The review included 31 studies that reported the psychometric properties of six measurement instruments (questionnaires, scales). Content validity, structural validity, internal consistency, reliability and cross-cultural validity were assessed for the included studies. The Childbirth Experience Questionnaire (CEQ/CEQ2) and Birth Satisfaction Scale - Revised (BSS-R) were the most commonly used questionnaires in the studies. CONCLUSIONS: Thorough testing of tools measuring women's satisfaction with childbirth, and adapting them to cultural and social contexts, is still essential. It is crucial that valid and reliable questionnaires are available for midwives in practice, for use in research, to inform clinical practice and for the results to help develop the services offered.
