Simple Summary The Carpathian water buffalo is a regional livestock resource in Central and Eastern Europe, but little is known about its genetic background. This study compared buffalo from Hungary and Romania using genome-wide marker data generated with a cattle genotyping array. The results show that both populations retain moderate genetic diversity. The Romanian animals had slightly higher diversity, whereas the Hungarian animals showed more long homozygous genome segments, which may indicate stronger recent relatedness or a more restricted breeding structure. The candidate regions for positive selection included genomic regions that may be associated with immune response, reproduction, growth, milk production and heat or cold tolerance. Because the marker array was designed for cattle and sample sizes differed between countries, the findings should be considered a first genomic baseline rather than final evidence of causal variants. The results can support future conservation planning and more detailed studies using buffalo-specific genomic tools.

Rhegmatogenous retinal detachment (RRD) is a vision-threatening retinal disorder in which successful anatomical reattachment does not always result in satisfactory functional visual recovery. Optical coherence tomography (OCT) has become an essential non-invasive imaging modality for evaluating retinal microstructure and identifying biomarkers associated with postoperative visual outcomes. This narrative review summarizes and critically evaluates current evidence regarding the prognostic significance of OCT biomarkers following RRD repair. Available studies indicate that primary outer retinal biomarkers, particularly the integrity of the ellipsoid zone (EZ) and external limiting membrane (ELM), are the most reliable predictors of postoperative best-corrected visual acuity. Preservation of these structures reflects photoreceptor viability and is strongly associated with improved visual recovery. Secondary biomarkers, including hyperreflective foci, intraretinal cystic changes, retinal folds, persistent subretinal fluid, and preretinal hyperreflective dots, provide complementary information regarding inflammatory activity, retinal remodeling, and postoperative complications such as epiretinal membrane formation. Although these biomarkers have considerable clinical value for prognostication, patient counseling, and postoperative monitoring, their interpretation is limited by heterogeneity among studies, differences in imaging protocols, and the lack of standardized assessment criteria. Future large-scale prospective studies are needed to validate OCT biomarkers and establish standardized approaches for their integration into routine clinical practice.

Background/Objectives: Hypertrophic cardiomyopathy (HCM) is a complex myocardial disease in which structural remodeling extends beyond conventional parameters such as maximal wall thickness (MWT). This study aimed to evaluate isoperimetric analysis as a geometry-based approach for characterizing left ventricular (LV) morphology and to compare its performance with fractal analysis in distinguishing HCM from non-HCM subjects. Methods: This retrospective study included 120 subjects (60 HCM and 60 controls) who underwent clinically indicated CMR. Endocardial contours were delineated on short-axis cine images at end-diastole. The isoperimetric index (IPI), cavity-corrected IPI (CC-IPI), and fractal dimension (FD) were calculated. Group comparisons, correlations, and receiver operating characteristic analyses were performed. Results: Patients with HCM showed significantly higher IPI and CC-IPI values than controls (p < 0.001), including in sex-stratified analyses. IPI and CC-IPI correlated strongly with MWT (r = 0.867) and LV mass index (r = 0.807 and 0.803, respectively), moderately with native T1 (r = 0.567), and weakly with end-diastolic volume index (r = 0.256 and 0.253, respectively) and stroke volume (r = 0.237 and 0.229, respectively). No association was observed with late gadolinium enhancement. IPI and CC-IPI showed a strong linear correlation (R2 = 0.997), with both indices demonstrating high discriminatory performance (AUC = 1.00). Conclusions: HCM is associated with notable alterations in LV endocardial geometry beyond myocardial hypertrophy alone. IPI and CC-IPI provide simple, size-normalized, and physiologically interpretable morphologic descriptors that complement conventional CMR parameters and FD-based contour complexity analysis.

Background/Objectives: Pharmacists play a key role in managing urinary tract infection (UTI) symptoms by providing medications, self-care advice, and over-the-counter treatments, while referring patients to a doctor when necessary. This study aimed to examine the practices of community pharmacists in managing UTI symptoms and to gain insight into their attitudes toward antibiotic use for this condition. Methods: A cross-sectional study was conducted among community pharmacists in Serbia using a previously validated online questionnaire, assessed for content and face validity and pilot-tested among pharmacists. Results: A total of 430 community pharmacists participated in the study. Patients more often consulted pharmacists before visiting a doctor than after (median 5 vs. 3 per week; p < 0.001). For uncomplicated UTIs, pharmacists primarily recommended increased fluid intake (92.8%), herbal teas (94.7%), and food supplements (85.6%), whereas for complicated UTIs, most referred patients to a doctor (95.4%). Attitudes, perceived competence, and support for over-the-counter antibiotic availability were significantly associated with gender, years of experience, and specialization. Pharmacists who agreed that antibiotics are the most effective treatment for uncomplicated urinary tract infections were more likely to refer patients to a doctor (p < 0.01). Conclusions: Pharmacists are frequently consulted for UTI management and emphasize non-antibiotic approaches for uncomplicated cases. Their attitudes influence counseling practices, highlighting the need for standardized UTI counseling services, antimicrobial stewardship education, and structured communication training to support appropriate antibiotic use.

Indoor air quality may be compromised by elevated radon levels, a naturally occurring radioactive gas. Prolonged exposure to increased radon levels can adversely affect human health. This paper presents the results of indoor radon activity concentration measurements conducted at 20 locations using a passive method. CR-39-based radon detectors were deployed over three different exposure periods, from January to April. The aim of the study was to compare and analyse average indoor radon activity concentrations obtained over different detector exposure periods, and to determine whether reliable information on indoor air quality can be obtained using shorter exposure durations. The measured indoor radon activity concentrations ranged from 6.0 to 727 Bq/m 3 , 10.1 to 561 Bq/m 3 , and 15.1 to 480 Bq/m 3 for the three-month, two-month, and one-month exposure periods, respectively. Comparative analysis of the results showed that the mean ratio of radon activity concentrations for one-month to two-month, two-month to three-month, and one-month to two-month exposure periods were 1.24, 1.57, and 1.85, respectively. To establish the relationship between radon activity concentrations obtained for different exposure periods, linear regression analysis was performed. The analysis of the estimated relative percentage differences showed that the results for different exposure periods agreed within ±20% at approximately 53% of the locations.

Cerebral visual impairment (CVI) is a complex neurological disorder that significantly affects the visual functioning of school-age children, often unrecognized within educational settings. The aim of this study was to determine the presence and frequency of specific visual behaviors associated with the risk of CVI in lower primary school students, and to examine differences in their recognition between parents and teachers. The study included 112 students from grades three through five, with data collectedusing an abbreviated version of the Screening for Cerebral Visual Impairmentquestionnaire. The results indicated that parents recognize specific visual behaviors considerably more often than teachers. Although this difference did not reach statistical significance, a borderline trend was observed. The findings suggest a need for enhanced teacher training, strengthened collaboration with parents, and the introduction of systematic screening procedures to enable timely identification of children at risk forCVI.Keywords:cerebral visual impairment, specific visual behaviors, visual difficulties

BACKGROUND Tuberculosis (TB) is the leading global cause of death from a single infectious agent. Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. METHODS We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. FINDINGS In 2023, there were an estimated 9·11 million (95% uncertainty interval 8·04-10·3) incident cases of all-form TB, 1·22 million (0·98-1·49) deaths, and 54·6 million (43·8-65·5) DALYs globally. HIV-related TB comprised 781 000 (690 000-879 000) incident cases and 210 000 (142 000-279 000) deaths, contributing 11·0 million (7·56-14·3) DALYs. MDR-TB accounted for 466 000 (198 000-1 080 000) incident cases, 102 000 (31 700-238 000) deaths, and 3·96 million (1·31-9·01) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19·2% (17·8-20·5) and deaths declined by 22·6% (4·7-35·7); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768 000 (592 000-970 000) and DALYs to 34·9 million (27·8-43·8) in 2023; MDR-TB deaths would decrease to 77 200 (23 400-183 000) and DALYs to 3·12 million (1·03-7·29). INTERPRETATION Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

ABSTRACT Background: Interaction between healthcare professionals and patients is a complex process influenced by communication, environmental, individual, and organizational factors. Objective: To synthesize qualitative and quantitative evidence and identify key characteristics of effective interaction between patients and nurse anesthetists during the perioperative period. Methods: A systematic literature search was conducted in PubMed, MEDLINE, CINAHL, Embase, and the Cochrane Library to identify qualitative and quantitative studies examining factors influencing interaction between patients and nurse anesthetists in the perioperative setting. Results: Both facilitators and barriers to effective interaction were identified. Facilitators included respectful, patient-centered care, a supportive work environment, and clear, timely communication. Barriers included negative staff attitudes, procedural stress, interpersonal conflicts, exposure to violence, and communication challenges such as low speech volume, unclear articulation, and limited language proficiency. Effective communication was associated with improved patient safety, enhanced team cohesion, and more efficient information exchange. However, increased reliance on advanced technology may reduce patient engagement and interpersonal communication within the healthcare team. Conclusion: Nurse anesthetists play a critical role in supporting patients during potentially stressful perioperative experiences. Organizational factors, time constraints, and communication strategies may influence the quality of patient–provider interaction. Further research is needed to determine how these factors can be optimized to improve perioperative care and patient outcomes.

Abstract Hemorrhagic cystitis (HC) in children is most associated with infection or treatment-related toxicity, whereas other cases remain uncommon. We report a 5-year-old boy presenting with recurrent painless gross hematuria in whom a structured, stepwise evaluation excluded glomerular, infectious, structural, and systemic causes. Cystoscopy revealed diffuse mucosal inflammation with focal hemorrhagic changes involving the bladder neck and posterior wall, consistent with noninfectious HC. In the absence of an identifiable etiology and with persistent symptoms, management was directed toward restoring urothelial barrier integrity using intravesical hyaluronic acid (HA). The clinical response was rapid, with resolution of gross hematuria after the first instillation, followed by sustained remission and progressive endoscopic improvement. The treatment was well tolerated, and the patient remained disease-free at 12 months of follow-up. This case highlights the diagnostic complexity of unexplained hematuria in children and supports a potential role of urothelial barrier dysfunction in the pathogenesis of noninfectious HC.

OBJECTIVE To investigate reported paper mill involvement among retracted systematic reviews and meta-analyses (SR/MAs), and to compare retracted SR/MAs with and without reported paper mill involvement with respect to temporal patterns, disciplinary profile, country recorded in the database, and retraction characteristics. STUDY DESIGN AND SETTING Cross-sectional study based on the Retraction Watch database. Records were screened to identify retracted SR/MAs. Reported paper mill involvement was assigned only when explicitly stated in the Retraction Watch record or associated retraction information; fake peer review was coded separately. Group comparisons used the Pearson chi-square and Mann-Whitney U tests. Associations with reported paper mill involvement were estimated using univariable Poisson regression with robust variance and reported as prevalence ratios (PRs) with 95% confidence intervals (CIs). These analyses were treated as exploratory, non-inferential internal contrasts within the dataset of already retracted SR/MAs. RESULTS Among 69,163 retracted publications in the Retraction Watch dataset, 1,071 (1.5%) were identified as retracted SR/MAs. Of those, 191 (17.8%) were paper mill-associated and 880 (82.2%) were not. In the database country field, China was recorded for 732/1,071 retracted SR/MAs (68.3%) and 177/191 SR/MAs with reported paper mill involvement (92.7%). The annual number of paper mill-associated SR/MAs peaked in 2023 (n=152). Within this restricted dataset, paper mill-associated SR/MAs had a longer median time to retraction (511 vs 459 days; p=0.024), more frequent results-related concerns (89.0% vs 30.0%), data issues (53.4% vs 17.5%), referencing concerns (53.9% vs 13.6%), and ethical concerns (8.9% vs 2.6%) (all p<0.001), and less frequent multi-country authorship (8.9% vs 17.6%; p=0.004). In univariable Poisson regression analyses restricted to retracted SR/MAs, larger observed proportions of reported paper mill involvement were seen among records linked to China in the database country field (PR 5.86, 95% CI 3.45-9.93), more recent publication years (PR 1.20 per 1-year increase, 95% CI 1.16-1.23), the medical broad domain (PR 3.66, 95% CI 1.66-8.08), and records with results-related concerns (PR 11.88, 95% CI 7.68-18.39). These PRs should not be interpreted as likelihoods, risks, or rates beyond the analyzed Retraction Watch subset. CONCLUSION In this Retraction Watch-based analysis, reported paper mill involvement was identified in 191/1,071 retracted SR/MAs (17.8%). These records were most often linked to China in the database country field (177/191; 92.7%) and clustered in recent years, particularly 2023. These findings should be interpreted as descriptive patterns within detected and retracted records, not as country-level rates, comparative performance indicators, or estimates of the true prevalence of paper mill activity.

Chronic kidney disease is increasingly recognised as a systemic disorder with important neurological consequences, including cognitive impairment. However, the field remains challenging because CKD-related cognitive decline involves diverse uremic toxins, overlapping vascular, inflammatory, metabolic, endothelial, and neurodegenerative pathways, inconsistent cognitive screening practices, and no unified treatment strategy. Within this context, the kidney–brain axis provides a useful framework for integrating renal dysfunction, toxin retention, systemic inflammation, blood–brain barrier disruption, and cognitive vulnerability. Of these mechanisms, uremic neurotoxicity offers a biologically credible connection between compromised renal clearance and cerebral dysfunction. Retained solutes such as indoxyl sulfate, p-cresyl sulfate, indole-3-acetic acid, trimethylamine-N-oxide, urea, guanidino compounds, lanthionine, quinolinic acid, and homocysteine may induce endothelial injury, oxidative stress, neuroinflammation, mitochondrial dysfunction, excitotoxicity, and glial activation. Although these pathways are supported by experimental and translational studies, direct causal evidence in humans remains limited, and most clinical data should currently be interpreted as associative rather than definitive proof of causality. These processes converge on neuronal and synaptic vulnerability and may elucidate the distinctive cognitive profile associated with chronic kidney disease, particularly deficits in attention, processing speed, and executive function. This review summarizes the most recent evidence on the epidemiology and clinical phenotype of cognitive impairment in chronic kidney disease. It also discusses the molecular and cellular mechanisms of uremic neurotoxicity and examines new biomarkers of the kidney–brain axis, including neurofilament light chain, glial fibrillary acidic protein, brain-derived neurotrophic factor, tight junction proteins, and uremic toxins. However, these biomarkers remain insufficiently validated for routine clinical use, as their interpretation is complicated by reduced renal clearance, systemic inflammation, comorbid vascular disease, methodological heterogeneity, and the lack of longitudinal studies linking biomarker changes to cognitive outcomes. Therapeutic strategies targeting uremic toxins remain compelling from a mechanistic standpoint, but they are not yet fully developed in clinical practice. Subsequent research ought to amalgamate toxin profiling, cognitive phenotyping, neuroimaging, endothelial and inflammatory biomarkers, alongside patient-centered outcomes. Integrating cognitive assessment into nephrology care may enhance risk stratification, collaborative decision-making, and personalised management for patients with chronic kidney disease.
