OBJECTIVES The objective of the present study was to explore whether gender differences exist in waist-to-height ratio (WtHR) values and to assess the correlation between WtHR and other obesity indicators after categorising older adults of Bosnian descent based on the presence or absence of abdominal obesity. METHODS The study included 151 inhabitants of the Geriatric Centre in Sarajevo, Bosnia and Herzegovina, aged 65 years and older (66 males and 85 females). Anthropometric indices and blood pressure values were measured by standard methods. WtHR was calculated using the following formula: waist circumference (WC) (cm)/height (cm). Differences between compared groups were analysed using the Student's t-test, Mann-Whitney U test or chi-square test. Correlations were assessed by Spearman's or Pearson's test. RESULTS Females had significantly higher WtHR values compared to males. Significant positive correlation was determined between WtHR and body mass index (BMI), WC, hip circumference (HC), neck circumference (NC), mid-upper arm circumference (MUAC), calf circumference (CC), and the weight-adjusted waist index (WWI) in both male and female elderly individuals. In elderly participants with abdominal obesity, there was a statistically significant positive correlation between WtHR and all of the tested anthropometric indices. Amongst elderly participants without abdominal obesity, a statistically significant positive correlation was observed between WtHR and BMI, WC, MUAC, and the WWI. However, no statistically significant correlations were observed between WtHR and HC, NC or CC in elderly participants without abdominal obesity. CONCLUSIONS The results of this study imply that WtHR is a valid parameter for assessing abdominal obesity in elderly individuals. The observed WtHR values indicate that women are at greater health risk than men. Given the high prevalence of sarcopenic obesity in older adults and the demonstrated limitations of BMI, we propose that WtHR should be incorporated into routine clinical practice for obesity assessment in this age group.

This study examines how the signal‐to‐noise‐interference ratio (SNIR) influences auditory performance and neural responses associated with listening effort (LE). A new dataset was collected from individuals with moderate hearing loss, all fitted with hearing aids (HAs). Participants listened to two competing audiobooks presented via front‐facing loudspeakers, while 16‐talker babble noise was delivered from background speakers. Six SNIR levels (5.47, −$$ - $$ 3.55, −$$ - $$ 2.13, −$$ - $$ 1.19, −$$ - $$ 0.64, and −$$ - $$ 0.27 dB) were tested. Participants were instructed to attend to one audiobook while ignoring the competing speech and background noise and were subsequently assessed on content of the attended speech and perceived LE. The performance results revealed a significant linear effect of SNIR on subjective ratings of LE and a primarily quadratic effect on comprehension questionnaire accuracy, suggesting that perceived effort decreases steadily with improving SNIR, while comprehension questionnaire performance exhibits a plateau at higher SNIR levels. The EEG analyses demonstrated a significant relationship between SNIR and local connectivity, specifically in the parietal electrodes and in the alpha frequency band. Further analysis confirmed that parietal local connectivity correlates linearly with subjective LE ratings. Moreover, spectral power analysis showed that parietal alpha power is not significantly related to SNIR, indicating that local connectivity may serve as a more sensitive neural marker. While local connectivity and alpha power may share some neural underpinnings, they offer complementary, yet non‐identical insights. These findings highlight the potential of local EEG connectivity as a reliable estimate of LE in acoustically challenging environments.

This study applied a virtual effect-directed analysis (vEDA) approach, integrating effect-based analysis and chemical screening, to identify bioactive compounds in rubber infill from artificial turf. Bioreporter assays targeting diverse toxicological endpoints were selected to detect a wide range of potential endocrine-disrupting and genotoxic compounds. Of 21 samples, all except one showed aryl-hydrocarbon receptor (AhR) activity (14-31,400 ng benzo[a]pyrene equivalents/g), four induced p53 activity (0.04-0.86 µg actinomycin D equivalents/g) and two showed estrogen receptor α (ERα) activity (530 and 1020 pg estradiol equivalents/g). Chemical analysis quantified up to 87 polycyclic aromatic compounds (PAC) and gas chromatography high-resolution mass spectrometry-based suspect screening yielded 281 tentative identifications. Annotation with bioassay activity data from databases and predictive models revealed 29 AhR-, 32 ERα- and 18 p53-active compounds. Univariate analysis was used to prioritize compounds for further chemical and toxicological confirmation. Eighteen AhR agonists were confirmed, contributing 0-98% to the observed AhR activity in the samples. Phenylamine additives, detected at high concentrations, exhibited low AhR activating potency and contributed < 1%. In contrast, methylated chrysene isomers elicited relatively high potencies and contributed substantially (≤65%) to the observed AhR activity. N-Isopropyl-N'-phenyl-p-phenylenediamine (IPPD) was confirmed as p53 active and explained ∼50% of the observed activity in the most p53-active sample. Styrene-butadiene rubber (SBR) showed higher AhR- and p53 activities and concentrations of quantified compounds than the alternative materials. The study highlights differences in chemical hazards among rubber infill materials and demonstrates the utility of vEDA as an early-warning tool for identifying compounds of concern.

In the rapidly evolving landscape of software engineering, the demand for robust and secure systems has become increasingly critical. This is especially true for self-adaptive systems due to their complexity and the dynamic environments in which they operate. To address this issue, we designed and developed the SAFT-GT toolchain that tackles the multifaceted challenges associated with ensuring both safety and security. This paper provides a comprehensive description of the toolchain's architecture and functionalities, including the Attack-Fault Trees generation and model combination approaches. We emphasize the toolchain's ability to integrate seamlessly with existing systems, allowing for enhanced safety and security analyses without requiring extensive modifications and domain knowledge. Our proposed approach can address evolving security threats, including both known vulnerabilities and emerging attack vectors that could compromise the system. As a use case for the toolchain, we integrate it into the feedback loop of self-adaptive systems. Finally, to validate the practical applicability of the toolchain, we conducted an extensive user study involving domain experts, whose insights and feedback underscore the toolchain's relevance and usability in real-world scenarios. Our findings demonstrate the toolchain's effectiveness in real-world applications while highlighting areas for future improvements. The toolchain and associated resources are available in an open-source repository to promote reproducibility and encourage further research in this field.

Background: African swine fever virus (ASFV) causes a fatal hemorrhagic disease in domestic pigs and wild boars. While live attenuated vaccines (LAVs) provide protection, their use raises safety concerns. Therefore, the aim of the present study was to identify viral B-cell antigens associated with protection and to test their potential using highly immunogenic vaccine delivery platforms. Methods: We employed a microarray of 169 ASFV proteins expressed in a cell-free prokaryotic system to identify immunodominant antigens using sera from immune pigs. Six structural proteins were selected and formulated into AP205 virus-like particles (VLPs). Additionally, replication-defective vesicular stomatitis virus (VSV)-based vaccine candidates expressing glycosylated CD2v and EP153R proteins were generated. Three groups of specific pathogen-free pigs were immunized with either VLP- or VSV-based vaccines and challenged with the virulent ASFV Georgia 2007 strain. Control groups included pigs immunized with the attenuated ASFV Estonia 2014 strain and a naïve group. Results: Most vaccine candidates induced detectable antibody responses against target ASFV proteins. However, neither VLP- nor VSV-based vaccines provided protection, as clinical scores, hematology, cytokine responses, and viremia levels were similar to those in the negative control group. In contrast, only the ASFV Estonia 2014 strain elicited a robust T-cell response and protective immunity. Conclusions: These findings highlight the challenges in identifying protective B-cell antigens of ASFV and emphasize the pivotal role of cellular immunity in mediating protection.

Background/Objectives: Heart rate variability (HRV) is a non-invasive marker of autonomic nervous system function with established prognostic value after acute coronary syndrome (ACS). The clinical relevance of temporal changes in short-term HRV remains insufficiently defined. This study evaluated short-term HRV dynamics and their association with mortality after ACS. Methods: This retrospective–prospective study included 230 patients with acute myocardial infarction. Five-minute resting ECG recordings were obtained on day 1 and day 21. Time- and frequency-domain HRV parameters were analyzed, and delta values were calculated. The primary endpoint was overall mortality. Survival was assessed using Kaplan–Meier analysis and Cox regression. Results: Patients who died during follow-up had lower HRV values on day 21 and more pronounced declines in selected parameters. In multivariable analysis, decreased ΔLF and shorter RR intervals independently predicted overall mortality. Conclusions: Short-term HRV provides a practical bedside assessment of autonomic function after ACS. Unfavorable temporal changes likely reflect persistent autonomic imbalance and may offer additional prognostic insight. Larger contemporary studies are needed to confirm these findings.

Background/Objectives: Aortic stenosis is associated with autonomic nervous system (ANS) imbalance, while diabetes mellitus is a major contributor to cardiac autonomic neuropathy. Their coexistence may result in more pronounced autonomic dysfunction not fully captured by conventional assessment. This study aimed to compare ANS function in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR), according to diabetes status. Methods: This cross-sectional study included 74 patients with severe aortic stenosis referred for TAVR, including 21 patients with diabetes mellitus. Autonomic function was evaluated using non-invasive ECG-based analysis, incorporating short-term and 24 h Holter-derived heart rate variability (HRV), nonlinear Poincaré plot indices, and deceleration and acceleration capacity. Ambulatory blood pressure monitoring and standard clinical and echocardiographic assessment were performed. Results: Patients with diabetes mellitus demonstrated significantly lower long-term HRV parameters and reduced nonlinear Poincaré plot indices compared with non-diabetic patients, indicating altered autonomic modulation. Short-term HRV showed similar trends without statistical significance. Echocardiographic severity of aortic stenosis and left ventricular systolic function were comparable between groups. Conclusions: Autonomic dysfunction appears to be more pronounced in patients with severe aortic stenosis and diabetes mellitus, predominantly affecting parasympathetic modulation. ECG-derived autonomic parameters may offer complementary insight into ANS involvement in this population and warrant further investigation.

BACKGROUND Newborn screening (NBS) for severe combined immunodeficiency (SCID) using T cell receptor excision circles (TREC) in dried blood spots (DBS) has been implemented in the U.S. and many other regions and countries globally. The Clinical Immunology Society (CIS) and the Association of Public Health Laboratories (APHL) jointly formed the SCID Harmonization Initiative to facilitate comparison of NBS reporting practices to promote global consensus and collaboration. OBJECTIVE To assess current NBS SCID practices using a global survey and to report the findings from the Phase 1 component. METHODS An eighteen-question survey was distributed to all known SCID screening programs worldwide. Only one response per region was analyzed. Examples of international screening algorithms were also solicited and included. RESULTS A total of 200 responses were received, of which eighty responses were unique and used for further analysis. Of the 39 non-U.S. countries, 15 (38%) reported national universal screening, and 24 (62%) reported regional, pilot, or other screening. Additional questions pertained to methodology and reporting with particular emphasis on communication of the clinical urgency of an abnormal TREC result. CONCLUSIONS This global survey confirmed that the approach to NBS SCID varies widely, underscoring the need for harmonization at multiple steps, particularly for reporting and interpretation. This is the first study to capture global NBS SCID practices, and these findings provide the basis for creation of a Phase 2 consensus reporting framework, which will be developed by the same SCID Harmonization Committee that created the current study.

Objective This study aimed to examine the associations between objective functional performance tests, clinical disability, MRI lesion characteristics, and recent relapse activity with basic and instrumental activities of daily living (ADLs/IADLs) in people with multiple sclerosis (MS). Materials and methods In this cross-sectional study including 65 patients with MS, clinical disability was assessed using the Expanded Disability Status Scale (EDSS), while functional performance was evaluated with the Timed 25-Foot Walk test (T25FW) and the 9-Hole Peg Test (9-HPT). Functional independence was assessed using the Barthel Index for basic ADL and the Lawton IADL scale. MRI lesion characteristics and relapse activity during the preceding two years were recorded. Associations were analyzed using Spearman correlation and multivariable linear regression models. Results Higher EDSS scores and worse T25FW and 9-HPT performance were associated with lower Barthel and IADL scores. In adjusted models, T25FW remained independently associated with basic ADL, while non-dominant hand 9-HPT was the strongest independent predictor of IADL; EDSS showed a weaker independent association with IADL. MRI lesion variables and recent relapse activity were not independently associated with functional independence. Conclusions Simple performance-based measures of gait speed and upper limb dexterity are strongly associated with real-life functional independence in MS and may contribute to a more comprehensive functional assessment in routine clinical practice.

Introduction: Stroke is a leading cause of long-term disability, and early functional prognostication is essential for individualized rehabilitation planning. Objective: The objective of the study is to examine the association between bedside motor and dexterity tests and standard outcome measures, and to evaluate their predictive value for functional independence in post-stroke patients. Materials and methods: This observational study was conducted at the Neurology Clinic, University Clinical Center Sarajevo, Sarajevo, Bosnia and Herzegovina, and included 61 patients with either ischemic or hemorrhagic stroke. Sociodemographic and clinical data were collected. Bedside functional assessments comprised the National Institutes of Health Stroke Scale (NIHSS), the Motor Assessment Scale (MAS), the Nine-Hole Peg Test (9-HPT) for upper limb dexterity, and the Berg Balance Scale (BBS). Functional outcomes were evaluated using the Barthel Index and the modified Rankin Scale (mRS) at admission and discharge. Associations between bedside assessments and functional outcomes were analyzed using correlation analyses, and independent predictors of functional independence were identified using multivariable linear regression models. Results: The mean age of participants was 74.8 ± 5.5 years, and 73.8% had ischemic stroke. Functional independence improved during hospitalization, with the Barthel Index increasing from 65.3 ± 22.9 at admission to 72.1 ± 26.5 at discharge. In multivariable regression analysis, the MAS emerged as the strongest independent predictor of functional independence measured by the Barthel Index (R² = 0.88, β = 1.49; p < 0.001). Performance on the 9-HPT using the non-dominant hand provided additional independent predictive value (β = -0.28; p = 0.048), while dominant-hand dexterity and balance performance were not significant predictors in the adjusted model. Conclusions: Simple bedside motor and dexterity assessments provide clinically relevant prognostic information in the early post-stroke phase. Their integration into routine clinical practice may enhance functional prognostication and support individualized rehabilitation strategies.
