<p>The traditional role of the fa&ccedil;ade, historically centered on providing protection against environmental conditions and reducing CO₂ emissions, has been significantly redefined through advances in software technologies and material sciences. These developments have led to the emergence of the fa&ccedil;ade system as a structurally independent component functioning as an active regulator of energy consumption, thereby creating new opportunities for research and innovation. One approach to studying these systems involves the application of folding principles derived from origami, which facilitates the design of modular geometric structures capable of dynamic environmental responses. Fa&ccedil;ades composed of interconnected, homogeneous elements can effectively regulate daylight penetration and thermal energy accumulation, particularly in zones exposed to direct external influences.</p> <p>To further develop such systems, it is essential to design an origami pattern whose geometric and mechanical characteristics can potentially respond to the given structural and technical challenges. This study explores the potential application of selected origami patterns in kinetic fa&ccedil;ade systems, with a focus on analyzing the actuation mechanisms that control the movement of geometric modules. Furthermore, the research evaluates the justification for integrating kinetic fa&ccedil;ade systems into contemporary architectural practice, with the aim of contributing to the development of sustainable, adaptive, and energy-efficient building envelopes.</p>

We determine how much TeV-scale new physics can deviate from flavor universality, $U(3)^5$, while respecting stringent bounds on flavor-changing neutral currents. The minimal continuous subgroup that must be approximately preserved is identified as $SU(2)_{q} \times U(1)_{X}$. With only a few symmetry-breaking spurions of $\mathcal{O}(10^{-2})$, all observed fermion hierarchies may be reproduced, offering a new perspective on the SM flavor puzzle. Remarkably, this framework provides structural flavor protection for generic TeV-scale new physics within the SMEFT, enlarging the space of collider-accessible scenarios beyond MFV and $U(2)^5$ and allowing for richer patterns of flavor violation.

Broadcasting meteorology is the part of meteorology which deals with communicating the data and information to the public. Nowadays it has gained momentum in parallel with the rise of extreme weather conditions, providing the beneficial opportunity to inform and educate the public. This implies breaking down abstract terminology and using the most advanced visual aids to simplify the complex language. However, the extreme weather perception is skewed due to climatic and meteorological illiteracy, the inability to comprehend the importance of the planetary energy budget and the overall contribution of greenhouse gases to the climate system. One of the greatest challenges for the broadcast meteorologists is the short lifespan of the forecasts – they may be verified in a few minutes, hours or days. Annually, it is not a rare occurrence that a frontal system is delayed or a convective storm degrades faster or changes the trajectory for which the broadcast meteorologist is crucified by the public. Therefore, narrow space and time references are often the biggest enemies. Another very recent issue is the colour bar scheme choice as the red and pink shades are to be the most fearmongering for the public and often used to be compared with past events. In July 2022, the conspiracy theories skyrocketed when the Met Office announced its first 40 °C in the UK, with the accusation of meteorologists being “harbingers of doom.” However, this was not an isolated case, as in April 2023, due to an exceptional heatwave for the time of the year, meteorologists at AEMET (Spanish Hydrometeorological Service) faced life threats, severely raising the pressure and affecting their contribution to society. Moreover, the probabilistic approach pours the confusion in the traditional weather reports and applications to the end users, often which cannot be perceived by the public to decide whether they will need an umbrella if the rain is expected, or not to stay dry. These issues remain the challenges for the foreseeable future, raising the concerns of presenting factual information, seeking alternative solutions for the numerical values in presenting the data to the public and the role of a broadcast meteorologis

Irritable bowel syndrome (IBS), a disorder of gut–brain interaction, is diagnosed using symptom-based Rome criteria. These criteria classify IBS patients into four subtypes in accordance to their stool patterns. However, whether this subtyping approach is based on true differences in the underlying biology of IBS patients, is unclear. Volatile organic compounds (VOCs) in the faecal headspace reflect both the gut microbial and host intestinal intraluminal processes and thereby may be used to study pathophysiological differences between IBS and its subtypes. We profiled faecal headspace VOCs in a cohort of 164 patients with IBS and 143 healthy controls using gas chromatography-mass spectrometry. Random forest models were employed to impute missing values and identify discriminatory VOCs to differentiate IBS patients from healthy controls. We corrected for faecal water content using partial least squares regression. Multivariate associations between the obtained volatile profiles and Rome III IBS subtypes were evaluated using regularized MANOVA. A total of 39 VOCs, including short-chain fatty acid esters, neurotransmitter-related metabolites, alcohols, and sulphides, were selected as significantly altered in patients with IBS. Our classification model achieved an area under the curve of 0.82 on both training and independent test sets, demonstrating robust separation between IBS patients and healthy individuals. However, VOC profiles did not associate to Rome III -based IBS subtypes. This study highlights the potential of faecal VOC profiling as a non-invasive tool for studying and characterizing IBS, yet they also reveal a disconnect between metabolic signatures and current stool-based subtypes. While the Rome criteria remain the clinical standard for diagnosis and subtyping of IBS, they offer limited insight into underlying disease mechanisms. Future research should focus on integrating VOC analysis with other omics approaches to refine IBS sub-classification into biologically relevant clusters, which may aid to improve personalized therapeutic strategies.

Summary Background The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023 estimates health loss from migraine, tension-type headache, and medication-overuse headache. This study presents updated results on headache-attributed burden from 1990 to 2023, along with clinical and public health implications. Methods Data on the prevalence, incidence, or remission of migraine, tension-type headache, and medication-overuse headache were extracted from published population-based studies. We used hierarchical Bayesian meta-regression modelling to estimate global, regional, and country-level prevalence of headache disorders. For the first time in GBD 2023, age-specific and sex-specific estimates of time in symptomatic state were applied by meta-analysing individual participant data from 41 653 individuals from the general populations of 18 countries from all parts of the world. Disability weights were applied to calculate years lived with disability (YLDs). Since medication-overuse headache is a sequela of a mistreated primary headache (due to medication overuse), its burden was reattributed to migraine or tension-type headache, informed by a meta-analysis of three longitudinal studies. Findings In 2023, 2·9 billion individuals (95% uncertainty interval 2·6–3·1) were affected by headache disorders, with a global age-standardised prevalence of 34·6% (31·6–37·5) and a YLD rate of 541·9 (373·4–739·9) per 100 000 population, with 487·5 (323·0–678·8) per 100 000 population attributed to migraine. The prevalence rates of these headache disorders have remained stable over the past three decades. YLD rates due to headache disorders were more than twice as high in females (739·9 [511·2–1011·5] per 100 000) as in males (346·1 [240·4–481·8] per 100 000). Medication-overuse headache contributed 58·9% of the YLD estimates for tension-type headache in males and 56·1% in females, as well as 22·6% of the YLD estimates for migraines in males and 14·1% in females. Interpretation Headache disorders, in particular migraine, continue to be a major global health challenge, emphasising the need for effective management and prevention strategies. Much headache-attributed burden could be averted or eliminated by avoiding overuse of medication (including over-the-counter medication), underscoring the importance of public education.

BACKGROUND Lower respiratory infections (LRIs) remain the world's leading infectious cause of death. This analysis from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023 provides global, regional, and national estimates of LRI incidence, mortality, and disability-adjusted life-years (DALYs), with attribution to 26 pathogens, including 11 newly modelled pathogens, across 204 countries and territories from 1990 to 2023. With new data and revised modelling techniques, these estimates serve as an update and expansion to GBD 2021. Through these estimates, we also aimed to assess progress towards the 2025 Global Action Plan for the Prevention and Control of Pneumonia and Diarrhoea (GAPPD) target for pneumonia mortality in children younger than 5 years. METHODS Mortality from LRIs, defined as physician-diagnosed pneumonia or bronchiolitis, was estimated using the Cause of Death Ensemble model with data from vital registration, verbal autopsy, surveillance, and minimally invasive tissue sampling. The Bayesian meta-regression tool DisMod-MR 2.1 was used to model overall morbidity due to LRIs. DALYs were calculated as the sum of years of life lost (YLLs) and years lived with disability (YLDs) for all locations, years, age groups, and sexes. We modelled pathogen-specific case-fatality ratios (CFRs) for each age group and location using splined binomial regression to create internally consistent estimates of incidence and mortality proportions attributable to viral, fungal, parasitic, and bacterial pathogens. Progress was assessed towards the GAPPD target of less than three deaths from pneumonia per 1000 livebirths, which is roughly equivalent to a mortality rate of less than 60 deaths per 100 000 children younger than 5 years. FINDINGS In 2023, LRIs were responsible for 2·50 million (95% uncertainty interval [UI] 2·24-2·81) deaths and 98·7 million (87·7-112) DALYs, with children younger than 5 years and adults aged 70 years and older carrying the highest burden. LRI mortality in children younger than 5 years fell by 33·4% (10·4-47·4) since 2010, with a global mortality rate of 94·8 (75·6-116·4) per 100 000 person-years in 2023. Among adults aged 70 years and older, the burden remained substantial with only marginal declines since 2010. A mortality rate of less than 60 deaths per 100 000 for children younger than 5 years was met by 129 of the 204 modelled countries in 2023. At a super-regional level, sub-Saharan Africa had an aggregate mortality rate in children younger than 5 years (hereafter referred to as under-5 mortality rate) furthest from the GAPPD target. Streptococcus pneumoniae continued to account for the largest number of LRI deaths globally (634 000 [95% UI 565 000-721 000] deaths or 25·3% [24·5-26·1] of all LRI deaths), followed by Staphylococcus aureus (271 000 [243 000-298 000] deaths or 10·9% [10·3-11·3]), and Klebsiella pneumoniae (228 000 [204 000-261 000] deaths or 9·1% [8·8-9·5]). Among pathogens newly modelled in this study, non-tuberculous mycobacteria (responsible for 177 000 [95% UI 155 000-201 000] deaths) and Aspergillus spp (responsible for 67 800 [59 900-75 900] deaths) emerged as important contributors. Altogether, the 11 newly modelled pathogens accounted for approximately 22% of LRI deaths. INTERPRETATION This comprehensive analysis underscores both the gains achieved through vaccination and the challenges that remain in controlling the LRI burden globally. Furthermore, it demonstrates persistent disparities in disease burden, with the highest mortality rates concentrated in countries in sub-Saharan Africa. Globally, as well as in these high-burden locations, the under-5 LRI mortality rate remains well above the GAPPD target. Progress towards this target requires equitable access to vaccines and preventive therapies-including newer interventions such as respiratory syncytial virus monoclonal antibodies-and health systems capable of early diagnosis and treatment. Expanding surveillance of emerging pathogens, strengthening adult immunisation programmes, and combating vaccine hesitancy are also crucial. As the global population ages, the dual challenge of sustaining gains in child survival while addressing the rising vulnerability in older adults will shape future pneumonia control strategies.

Abstract Introduction This study examines the prevalence of bullying among primary school students in the Federation of Bosnia and Herzegovina (FBiH), analyses gender differences, and assesses its association with traumatic and psychosomatic symptoms. Methods This cross-sectional study was conducted among students in grades seven to nine. Participants were categorised based on bullying involvement as victims, bullies, bully/victims, or uninvolved. Validated self-report questionnaires were used to measure bullying exposure and assess psychosomatic and trauma-related symptoms. Results In total, 13.3% of the students identified as victims, 3.1% as bullies, and 4.4% as both. Victims and bully/victims reported significantly higher rates of psychosomatic symptoms (e.g., pain, fatigue, gastrointestinal complaints) and trauma-related symptoms (e.g., anxiety, depression, dissociation) than uninvolved students. Bully/victims showed the highest overall burden, suggesting compounded vulnerability. Conclusions These findings highlight the urgent need for trauma-informed, context-sensitive prevention strategies. Training school staff to recognise emotional and somatic distress, integrating basic screening tools into school and primary health services, and enhancing intersectoral collaboration are critical steps in ensuring early identification and adequate support for affected students.

Treatment of Clostridioides difficile infections in University Clinical Hospital Mostar from an economic perspective Clostridioides difficile is the most prominent pathogen directly tied to a healthcare system and proven to be one of the main causes of high economic impacts. It results in a frequent need for hospitalization, including the treatment of sepsis and post-acute care, and requires an extended number of days spent at the hospital. In addition to the costs of the medicine and laboratory analysis, extended hospitalization is the key component of the high healthcare expenses. The rational use of antibiotics, mandatory implementation of general hygiene measures, like washing hands, and disinfecting surfaces can significantly contribute towards hospital's overall expenses. This is particularly important for those in contact with an infected patient or with a patient suspected of having CDI. These basic measures establish security systems in the prevention of CDI. Proper managing and forecasting of the costs on the annual level for each individual healthcare institution is a necessary measure.

Introduction: Polycystic ovary syndrome (PCOS) represents a state of androgen-driven metabolic dysregulation where visceral adiposity and inflammation critically define cardiometabolic risk. Visceral adiposity is not a bystander in PCOS; it is an active endocrine organ driving insulin resistance, low-grade inflammation, and androgen persistence. Interventions that reverse adipocyte hypertrophy and inflammatory signaling may therefore alter the metabolic trajectory of PCOS. Beyond its chronobiotic role, melatonin exerts profound metabolic actions via MT1/MT2 receptors in adipose tissue, modulating oxidative stress and inflammatory gene expression. Yet its direct impact on androgen-induced visceral adiposity remains unclear. Aim: The present study aimed to evaluate the effects of melatonin, metformin, and their combination on visceral fat accumulation in a testosterone-induced PCOS rat model. Material and methods: Thirty prepubertal female Wistar rats were randomized into five groups (n=6): control, PCOS (testosterone 20 mg/kg/day), PCOS+metformin (500 mg/kg/day), PCOS+melatonin (2 mg/kg/day), and PCOS+melatonin+metformin. Treatments lasted 36 days. Estrous cyclicity was monitored by daily vaginal cytology, and somatometric parameters were recorded weekly. On day 36, serum, ovaries, and visceral fat were collected for biochemical and histological analysis. Results: Vaginal smear changes and ovarian pathological alteration due to prolonged testosterone exposure confirmed the successful induction of the PCOS model. Measures of central adiposity, including abdominal circumference and the TC/AC ratio, were significantly higher in the PCOS model than in controls (p < 0.001). Abdominal circumference (AC) increase was greatest in the PCOS model (p < 0.001), while all treatment groups showed significant reductions, most notably in the melatonin + metformin group, followed by melatonin monotherapy and then metformin (all p < 0.001 vs. PCOS). Melatonin was more effective than metformin (p=0.029). AC/TC reduction was greatest in the combined treatment group (p < 0.05). Total weight gain among groups did not reach statistical significance. While total visceral fat weight did not differ among groups, histology revealed a marked reduction in adipocyte number in treated animals, most pronounced in the melatonin group (p < 0.033). Conclusion: Our findings identify melatonin as a metabolic modulator of androgen-driven adiposity, supporting its potential as an adjunctive therapy targeting visceral fat and inflammation in PCOS

Abstract Due to an ongoing energy crisis and fluctuating energy prices, the prerequisites for maintaining optimal indoor environmental quality (IEQ), a critical determinant of productivity, cognitive performance, and overall well-being, have been significantly disrupted. This study focuses on examining determinants of thermal comfort, a subjective evaluation of the thermal environment and a key component of IEQ. Through a survey of employees and users of public buildings in Bosnia and Herzegovina, the research employs a four-stage regression analysis to identify the main predictors of thermal comfort. Although 71.33% of respondents report satisfaction with the heating system, only 43.13% find the heating to be adequate, with the optimal perceived temperature averaging 21.66°C. The results show that key factors influencing thermal comfort include thermal sensation, thermal memory, gender, and respondent type (employee versus user). These seminal results could offer valuable productivity and financial implications for energy savings, especially for budgetary policymakers aiming to reduce energy consumption as well as for public sector management and public institutions seeking to improve well-being and productivity.

Anterior clinoidal meningioma (ACM) remains a challenging lesion to treat surgically due to its intricate neurovascular relationships with surrounding anatomy and often presents with ipsilateral visual loss. Anterior clinoidectomy (AC) by skilled skull base surgeons enables early optic nerve (ON) decompression, tumor devascularization, and radical tumor resection. The authors provide an update on ACM surgery, current views on the role of AC and its impact on outcomes in surgical treatment, as well as a new 2 stage 4 by 4 step concept of ON decompression involving AC. A systematic review of PubMed and meta-regression of surgically treated ACMs was performed. In total, 908 patients were analyzed; 415 (45.7%) underwent routine AC (performed in all cases) and 493 (54.3%) underwent selective AC (planned preoperatively). The routine AC cohort showed higher risk for new cranial-nerve (CN) deficits (12.5% vs. 3.0%; p < 0.001), vascular complications (6.7% vs. 3.3%; p = 0.02), and new focal neurological deficits (5.5% vs. 2.3%; p = 0.04). No differences were found in visual outcomes, gross-total resection, mortality, recurrence, or other major complications. Random-effects meta-regression of routine AC showed increased odds of new CN deficit (odds ratio [OR], 3.34; 95% confidence interval [95% CI], 1.51–7.38; p = 0.005; heterogeneity [I2] = 60.5%) and vascular complication (OR, 2.59; 95% CI, 1.05–6.38; p = 0.04; I2 = 47.8%), with moderate and substantial heterogeneity among routine AC studies, respectively. In experienced hands, AC remains an invaluable tool for ACM treatment as it offers more consistent tumor devascularization, prevention of tumor recurrence, optic nerve decompression, and increased working space, which facilitates optimal tumor resection and better long‐term control and functional outcome. We propose a new didactical structured concept of routine AC via 2-stage, 4 by 4 steps to improve the utility of AC and decrease associated operative risks compared to selective AC.
