AIM: This study aimed to identify sleep profiles in a representative sample of Slovak adolescents and investigate their associations with adiposity indicators and cardiorespiratory fitness. METHODS: Data from the 2022 Health Behaviour in School-aged Children (HBSC) study conducted in Slovakia were analysed. Survey questions on sleep duration and problems from the entire HBSC sample (n = 8906) were used to identify sleep profiles. Associations with adiposity indicators and cardiorespiratory fitness were investigated in a subsample of 924 adolescents (average age 13.3 ± 1.48; 56.2% boys) who completed the HBSC survey, bioimpedance analysis, and 20-metre shuttle run test. RESULTS: Three sleep profiles were identified-optimal sleepers, optimal sleepers with sporadic sleep problems and poor sleepers. Crude models showed that poor sleepers had significantly higher body fat percentage and fat mass index, along with lower cardiorespiratory fitness, compared to optimal sleepers. After adjustment, only the association between sleep profiles and cardiorespiratory fitness remained significant. CONCLUSION: The observed associations between sleep profiles and cardiorespiratory fitness may help better target future intervention resources towards adolescents with low cardiorespiratory fitness levels.

Cieľom štúdie je overenie psychometrických vlastností škály CAV, určenej na mapovanie skúseností s kyberagresiou a kyberviktimizáciou. Nástroj je tvorený 24 položkami rozdelenými do dvoch subškál: Kyberagresia (CAV-CB; 12 položiek) a Kyberviktimizácia (CAV-CV; 12 položiek). Výskumný súbor pozostával z N = 5 159 respondentov/tiek vo veku od 14 do 18 rokov (M = 16,06; SD = 1,159), pričom 51,3 % tvorili chlapci a 48,7 % dievčatá. Na overenie faktorovej štruktúry bola použitá konfirmačná faktorová analýza (CFA), aplikovaná metódou DWLS s robustnou korekciou, pričom posudzované boli štandardné indexy zhody. Na základe výsledkov analýz bol podporený dvojfaktorový model: χ2 (251) = 530,064; p < 0,001; CFI = 0,993; TLI = 0,992; RMSEA = 0,016 (90% CI: 0,014 – 0,018). Analýza invariancie merania bola vykonaná vzhľadom na rod a vek, pričom testované boli konfigurálna, metrická, skalárna a striktná invariancia. Hodnoty testov invariancie merania pri porovnaní podľa rodu a veku boli konzistentné so všetkými modelmi invariancie, čo umožňuje porovnávanie skóre medzi skupinami. Reliabilita škály bola hodnotená pomocou Cronbachovho α a McDonaldovho ω, pričom faktory mali uspokojivú vnútornú konzistenciu (CAV-CB: α = 0,907, ω = 0,908; CAV-CV: α = 0,920, ω = 0,921). Kyberagresia signifikantne korelovala s kyberviktimizáciou (r = 0,699; p < 0,001), čo naznačuje vzájomnú súvislosť medzi oboma faktormi. Percentilová distribúcia skóre v populácii dospievajúcich umožnila stanoviť orientačné normo-referenčné hranice pre subškály CAV-CB a CAV-CV, na základe ktorých bola vytvorená trojstupňová klasifikácia úrovne expozície určená na výskumné a preventívne účely.

The aim of this study was to evaluate the psychometric properties of the Cyber-Aggression and Cyber- Victimization Scale (CAV), which was developed to assess adolescents’ experiences with cyber-aggression and cyber-victimisation. The instrument consists of 24 items divided into two subscales: Cyber-aggression (CAV-CB; 12 items) and Cyber-victimization (CAV-CV; 12 items). The research sample comprised N = 5,159 adolescents aged 14 to 18 years (M = 16.06; SD = 1.159), with 51.3%boys and 48.7%girls. Confirmatory factor analysis (CFA) was used to assess the factor structure, employing the DWLS method with robust corrections and evaluating standard goodness-of-fit indices. The analysis supported a two-factor model: χ2 (251) = 530.064; p < .001; CFI = .993; TLI = .992; RMSEA = .016 (90% CI: .014–.018). Measurement invariance was tested across gender and age groups, including configural, metric, scalar, and strict invariance. Invariance testing results indicated acceptable fit for all models, supporting the comparability of scores across groups. Reliability was assessed using Cronbach’s alpha and McDonald’s omega, both indicating satisfactory internal consistency (CAV-CB: α = .907, ω = .908; CAV-CV: α = .920, ω = .921). Cyberaggression showed a significant correlation with cybervictimization (r = .699; p < .001), indicating a substantial relationship between the two constructs. The percentile distribution of scores in the adolescent population made it possible to establish provisional norm-referenced cut-off points for the CAV-CB and CAV- CV subscales, based on which a three-level classification of exposure was created for research and preventive purposes.

Cognitive flexibility (CF) is the ability to adapt cognitive strategies according to the changing environment. The deficit in CF has often been linked to various neurological and psychiatric disorders including schizophrenia. However, the operationalization and assessment of CF have not been unified and the current research suggests that the available instruments measure different aspects of CF. The main objective of the present study was to compare three frequently used neuropsychological measures of CF-Wisconsin Card Sorting Test (WCST), Trail Making Test (TMT) and Stroop Color and Word Test (SCWT) in a population of patients (N = 220) with first-episode schizophrenia spectrum disorders in order to evaluate their convergent validity. The hypothesis of an underlying latent construct was tested via a confirmatory factor analysis. We used a one-factor CF model with scores from WCST, SCWT and TMT as observed variables. The established model showed a good fit to the data (χ2 = 1.67, p = 0.43, SRMR = 0.02, RMSEA = 0.0, CFI = 1.00). The highest factor loading was found in WCST as CF explained most of the variance in this neuropsychological measure compared to the other instruments. On the other hand, a TMT ratio index and a SCWT interference demonstrated lowest loadings in the model. The findings suggest that not all the frequently used measures share an underlying factor of CF or may capture different aspects of this construct.

Introduction: The ability to self-care is considered essential in heart failure management. One of the valid and reliable instruments that allow the measurement of heart failure self-care behaviour is the European Heart Failure Self-Care Behaviour Scale (EHFScBS-9). Objective: To adapt and assess psychometric properties of the Slovak version of the EHFScBS-9. Methods: In this descriptive validation study, 122 Slovak heart failure patients completed the EHFScBS-9, the Cardiac Self-Efficacy Questionnaire (CSEQ), and Personal Well-being Index (PWI). Item analysis, confirmatory factor analysis (CFA), and convergent and discriminant validity were evaluated. Cronbach's alpha was calculated to assess reliability. Results: The results of CFA confirmed a good fit of the two- respectively three-factor structure of the Slovak EHFScBS-9. Convergent validity was confirmed by positive correlation between the Slovak EHFScBS-9 and the CSEQ. Discriminant validity was supported by poor correlation between EHFScBS-9 and PWI. Cronbach's alpha coefficient for the total EHFScBS-9 instrument of Slovak version was 0.77. Conclusion: The Slovak version of the EHFScBS-9 instrument is valid and reliable to measure self-care behaviour in heart failure patients.

Miřátský, P, Hank, M, Gryc, T, Brožka, M, Cabell, L, Escamilla, R, Zahálka, F, and Malý, T. Fitness differences among professional firefighters utilizing various conditioning regimens throughout the year. J Strength Cond Res 39(7): e898-e908, 2025-The aim of this study was to compare selected parameters of physical fitness of Czech frontline professional firefighters ( n = 92), who performed various physical activities according to their preferences within their regular physical preparation for 1 year. These firefighters were assigned to 1 of 3 groups based on their training preferences and sport focus: General Sports Activities (GSA; n = 30), Fire Sport (FS; n = 36), and Toughest Firefighter Alive (TFA; n = 26). All subjects completed (in period September) a battery of laboratory fitness tests including body composition, lower limb muscular strength and power, and cardiorespiratory fitness. Firefighters in the FS and TFA groups were found to have significantly higher values ( p < 0.01) for the following variables: fat-free mass, isokinetic strength, muscle power, maximum aerobic capacity, minute ventilation, and heart rate at the anaerobic threshold than their counterparts in the GSA group. There were no significant differences in body mass ( p = 0.21) and body mass index (BMI) ( p = 0.48) between the firefighter groups. Professional frontline firefighters' level of physical fitness is improved by the incorporation of specific physical training activities, duties, and disciplines. This can have a direct impact on frontline firefighters' capacity to fight fires safely and effectively.

OBJECTIVE: Benefits of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in kidney transplant (KT) recipients have not been adequately studied. METHODS: We retrospectively examined the effects of GLP-1 RA on mortality, kidney outcomes and metabolic parameters in KT recipients with type 2 diabetes mellitus (T2DM) treated versus not treated with GLP-1 RA. A reference group of KT recipients not treated with GLP-1 RA was used for comparison. Data were analyzed using analysis of variance, χ2 tests, and generalized estimating equation models. GLP-1 RA was used as a time-dependent model in Cox regression modeling. For survival analysis, the final model fitting was stratified by race-ethnicity. RESULTS: Seventy-seven KT recipients with T2DM were treated with GLP-1 RA for at least 12 months. Reference group included 2094 patients not on GLP-1 RA. The mean (SD) age at transplant was 57.9 (9.5) and 60.8 (9.5) years for the treatment and reference groups, respectively. Median follow-up time from the index date for mortality was 1.5 (IQR 0.99, 2.4) in the treatment and 5.8 (IQR 3.4, 9.1) years in the reference group. GLP-1 RA use was associated with improved survival (P = .049), decreased urine albumin to creatinine ratio (net reduction of 10.62 mg/g per year, P = .003), slower estimated glomerular filtration rate decline (1.04 vs 1.56 mL/min/1.73 m2 per year, P = .04), and lower troponin levels. CONCLUSIONS: GLP-1 RA in KT recipients with T2DM was associated with reduced mortality, and improved kidney function compared to the reference group. Larger, prospective studies are needed to fully evaluate the risks and benefits of GLP-1 RA therapy in KT recipients.

AIMS: To evaluate the prevalence, long-term mortality, and clinical characteristics in total cavopulmonary connection patients with excellent functional outcomes. METHODS AND RESULTS: A retrospective study of cardiopulmonary exercise test results in 288 patients after total cavopulmonary connection from a single-centre nationwide database. A subgroup of 88 (30.6%) patients (45 women; 51.1%), at a median age 13.0 [interquartile range 11.0; 18.0] years achieved ≥80% of predicted VO2peak value (Super-Fontan phenotype). Survival free from death or heart transplantation 20 years after surgery was 100.0% in the Super-Fontan group versus 94.0% in the rest of the cohort (p = 0.04). Super-Fontan patients were younger, had lower body mass index, lower regurgitant fraction on atrioventricular valve, and larger preoperative McGoon ratio than the rest of the cohort (p = 0.002, p < 0.0001, p = 0.004, and p = 0.04, respectively). Females and tricuspid atresia patients were significantly more prevalent in the Super-Fontan group than in the rest of the cohort (p = 0.02 for both). There was no difference regarding systemic ventricle morphology, fenestration presence, or ejection fraction of systemic ventricle between the Super-Fontan group and the rest of the total cavopulmonary connection cohort (p = 0.06, p = 0.09, and p = 0.64, respectively). CONCLUSIONS: The subgroup of Super-Fontan patients has unique clinical characteristics when compared to the rest of the total cavopulmonary connection nationwide cohort. Besides superior VO2peak results, Super-Fontan patients tend to have lower long-term mortality, body mass index, and atrioventricular valve, greater preoperative pulmonary dimensions, and a higher prevalence of females and tricuspid atresia patients. There was no variance in morphology of the systemic ventricle, or presence of fenestration.

BACKGROUND: In the era of standardized outcome reporting, it remains unclear if widely used comorbidity and health status indices can enhance predictive accuracy for morbidity and long-term survival outcomes after radical cystectomy (RC). PATIENTS AND METHODS: In this monocentric study, we included 468 patients undergoing open RC with pelvic lymph node dissection for bladder cancer between January 2009 and December 2017. Postoperative complications were meticulously assessed according to the EAU guideline criteria for standardized outcome reporting. Multivariable regression models were fitted to evaluate the ability of ASA physical status (ASA PS), Charlson comorbidity index (± age-adjustment) and the combination of both to improve prediction of (A) 30-day morbidity key estimates (major complications, readmission, and cumulative morbidity as measured by the Comprehensive Complication index [CCI]) and (B) secondary mortality endpoints (overall [OM], cancer-specific [CSM], and other-cause mortality [OCM]). RESULTS: Overall, 465 (99%) and 52 (11%) patients experienced 30-day complications and major complications (Clavien-Dindo grade ≥IIIb), respectively. Thirty-seven (7.9%) were readmitted within 30 days after discharge. Comorbidity and health status indices did not improve the predictive accuracy for 30-day major complications and 30-day readmission of a reference model but were associated with 30-day CCI (all P < .05). When ASA PS and age-adjusted Charlson index were combined, ASA PS was no longer associated with 30-day CCI (P = .1). At a median follow-up of 56 months (IQR 37-86), OM, CSM, and 90-day mortality were 37%, 24%, and 2.9%, respectively. Both Charlson and age-adjusted Charlson index accurately predicted OCM (all P < .001) and OM (all P ≤ .002) but not CSM (all P ≥ .4) and 90-day mortality (all P > .05). ASA PS was not associated with oncologic outcomes (all P ≥ .05). CONCLUSION: While comorbidity and health status indices have a role in predicting OCM and OM after RC, their importance in predicting postoperative morbidity is limited. Especially ASA PS performed poorly. This highlights the need for procedure-specific comorbidity assessment rather than generic indices.

OBJECTIVES: The Short Form-8 (SF-8) is a widely used 8-item tool for health-related quality of life assessment. This study aimed to evaluate the psychometric properties of the Slovak version of the SF-8 in a population sample. METHODS: A cross-sectional survey on a Slovak representative sample (n = 1018; mean age 46.24 ± 16.56 years; 51.3% women) monitoring health and well-being was performed in 2019. Exploratory network analysis and confirmatory factor analysis were used to assess the construct validity of the scale. Reliability and sociodemographic differences were evaluated. RESULTS: A 2-factor model had an adequate fit to the data [χ2(19) = 186.2, P < .001, comparative fit index = 0.998, Tucker-Lewis index = 0.997, root mean square error of approximation = 0.093, standardized root mean of residuals = 0.039], with high reliability (α = 0.93, ω = 0.95). The physical component score and mental component score (MCS) were negatively associated with the presence of chronic health conditions. Lower physical component score and MCS were associated with higher age (P < .001), and lower MCS were associated with female gender (P < .001). CONCLUSIONS: The Slovak version of the SF-8 represents a valuable tool for measuring health-related quality of life in the Slovak population in both practice and research.
