Pathological studies suggest that multiple sclerosis (MS) lesions endure multiple waves of damage and repair; however, the dynamics and characteristics of these processes are poorly understood in patients living with MS.

The association between hypertension as a pre-existing comorbidity and the severe form of coronavirus disease 2019 (COVID-19) remains unclear due to the contradictory results of previously published studies. The present study evaluated the predictive significance of hypertension in the incidence of complications among critically ill patients with COVID-19. The present study included 372 critically ill adults with COVID-19 pneumonia, hospitalized between January 1 and December 31, 2021. The study cohort was divided into the hypertension group (HTA group), which included 245 patients with a history of hypertension, or a non-HTA group (control group), which included 127 patients without hypertension. The incidence of complications was retrospectively extracted from medical records and compared between groups. Multivariate regression analysis (adjusted for potential confounders) and receiver operating characteristic (ROC) curve analysis determined the predictive significance of hypertension on the incidence of complications. The patients in the HTA group were more likely to receive invasive mechanical ventilation [odds ratio (OR), 1.696; P<0.02], develop sepsis (OR, 1.807; P<0.01) and develop complications (OR, 3.101; P<0.001). Hypertension was an independent positive predictor for invasive mechanical ventilation [area under the curve (AUC), 0.67; positive predictive value (PPV), 71.7%; P<0.05], sepsis (AUC, 0.69; PPV, 77.5%; P<0.026) and total complications per patient (AUC, 0.71; PPV, 81.4%; P<0.001). On the whole, the data of the present study indicate that a history of hypertension should be considered as an independent clinical predictor of a higher incidence of complications in critically ill patients with COVID-19. Patients with pre-existing hypertension and a diagnosis of COVID-19 require timely identification, additional attention and treatment to avoid a critical course and help improve outcomes.

Antimicrobial resistance (AMR) is a global concern, necessitating the understanding of utilisation patterns and their rationale. Pilot studies have been conducted in a rural province in South Africa to determine the extent of self-purchasing of antibiotics by patients from independent and chain pharmacies. It is imperative to understand the extent of knowledge and concerns of patients regarding the key aspects of antibiotic use and AMR, and potential language barriers, when pharmacists and their assistants are discussing the key aspects with patients. Consequently, the aim was to pre-test a patient questionnaire translated in three native languages building on the findings from the English language pilot. The English patient questionnaire (Parts 1 and 2) was translated to Sepedi, Tshivenda and Xitsonga. In total 30 patients were interviewed (5/language for Part 1 and Part 2 respectively) when leaving 10 chain and independent pharmacies. This was followed by interviews with patients to evaluate their understanding of questions and key concepts. Eleven of 15 patients interviewed for Part 1 received antibiotics, including 8 without a prescription. Only independent pharmacies (8/10) dispensed antibiotics without prescriptions. Interviews revealed concerns about antibiotic knowledge and AMR and that certain terms including ‘antibiotic’ and ‘AMR’ posed challenges with patient understanding of the purpose of antibiotics. For instance, one patient self-purchased antibiotics for ‘cleansing’ of sexually transmitted infections. The questionnaires in the native languages were subsequently revised so that explanations for terms, including ‘antibiotic’ and ‘AMR’ will be provided in the main study. Similar to the previous pilot studies, self-purchasing of antibiotics was observed among independent pharmacies, although at varying rates, with similar indications. Continued health literacy education for pharmacists and patients, especially with native language communication, are needed to address current challenges and will be explored in the main study.

In deaf students, there is no contextual understanding and recognition of word types through linguistic competence testing compared to the hearing population, because 67.10% do not understand, and 10.00% of deaf respondents partially understand the contextual application of word types in a written text task. In written communication, deaf students use nouns (65.70%), pronouns (34.30%), verbs (45.7%), adjectives (28.60%), adverbs (22.90%), prepositions (54.30%), exclamations (15.70%), particles (12.90%) and numbers (32.90%). The aim of the study was to examine the factor solutions of quantitative indicators of contextual understanding of the word’s types used and the relation of isolated factors of the words types words in the written text task of deaf students. The study was conducted on a sample of 140 respondents. The first subsample of respondents, the experimental group consisted of 70 deaf students, and the second subsample, the control group of 70 hearing students, of the same chronological age and gender. The measurement instrument “Test of comprehension of the written form of expression” was applied. The collected data were processed using the method of oblique rotation and the method of factor analysis. The results of the study showed that the language discourse of the deaf in the quantitative use of word types in the written form of expression is organized significantly differently compared to the hearing population. By factor analysis, three main factors were isolated in the deaf population, and four main factors were isolated in the hearing population. Considering the saturation of variability, it is possible to accurately determine in practice the direction of teaching deaf children the types of words in their native language. Isolated factors are part of separate, statistically unrelated entities in both deaf and hearing respondents and confirm the justification of successive teaching of the deaf respondents according to the types of words that are present in the comparative analysis of hearing respondents.

A major challenge in autonomous flights is unknown disturbances, which can jeopardize safety and cause collisions, especially in obstacle-rich environments. This letter presents a disturbance-aware motion planning and control framework for autonomous aerial flights. The framework is composed of two key components: a disturbance-aware motion planner and a tracking controller. The motion planner consists of a predictive control scheme and an online-adapted learned disturbance model. The tracking controller, developed using contraction control methods, ensures safety bounds on the quadrotor’s behavior near obstacles with respect to the motion plan. The algorithm is tested in simulations with a quadrotor facing strong crosswind and ground-induced disturbances.

In 2004, the Commission for the Preservation of National Monuments declared the "Architectural Complex of Husejnija (Husein-kapetan Gradaščević) Mosque in Gradačac" a national monument of Bosnia and Herzegovina. The mosque belongs to the type of central domed mosque with a portico covered by three small domes. In September/October 2023, cracks were observed on six arches, the capitals of two columns, and the base of one column in the portico of the mosque. Geotechnical investigative works included the creation of three excavations and two boreholes with continuous Standard Penetration Tests (SPT). The excavations reveal layers below the ground level, consisting of a well-bound sandy artificial fill from the ground surface to a depth of 1.35 meters, a layer of poorly bound artificial stony material from 1.35 to 2.45 meters, and a layer of natural clay at greater depths. It is assumed that over time, due to water seepage from the hillside and rainfall runoff from the mosque, there has been a change in the physical-mechanical properties of the foundation soil and partial settling of the portico structure. In addition to the existing channel on two sides of the mosque, a drainage ring around the building and a drainage curtain on the uphill slope have been designed. Also, underpinning of the portico foundations in alternating segments has been designed to strengthen the stone masonry layer and prevent further settling and development of cracks in the portico elements. After the works are completed, a 12-month monitoring period is planned, followed by an analysis and repair of the cracks.

Objectives Childhood-onset systemic lupus erythematosus (cSLE), representing 15%–20% of individuals with SLE, has been difficult to study globally due to differences between registries. This initiative, supported by Childhood Arthritis Rheumatology Research Alliance (CARRA) and Paediatric Rheumatology European Society (PReS), aims to create Core and Expanded cSLE Datasets to standardise and enhance research worldwide. Methods 21 international cSLE experts and 4 patients participated in a Delphi process (questionnaires, 2 topic-specific focus groups and 3 virtual consensus meetings) to create 2 standardised cSLE datasets. The Core cSLE Dataset was designed to include data essential to meaningful clinical research across many settings. The Expanded cSLE Dataset was designed for centres able to consistently collect data to address broader research questions. Final data items for the Core and Expanded datasets were determined by consensus defined as >80% agreement) using an adapted nominal group technique and voting. Results The resulting Core cSLE Dataset contains 46 items, including demographics, clinical features, laboratory results, medications and significant adverse events. The Expanded cSLE Dataset adds 26 additional items and includes patient-reported outcomes. Consensus was also achieved regarding the frequency and time points for data collection: baseline, quarterly follow-up visits, annually and flare visits. Conclusion Standardised Core and Expanded cSLE Datasets for registry-based international cSLE research were defined through the consensus of global experts and patient/caregiver representatives, endorsed by CARRA and PReS. These datasets incorporate disease-specific and patient-specific features, optimised for diverse settings to facilitate international collaborative research for children and adolescents with SLE worldwide.

Enhancing communication between Vulnerable Road Users (VRUs) and Unmanned Automated Vehicles (UAVs) has significant potential to improve road safety. The need for this communication is due to the fact that VRUs will no longer be able to establish physical eye contact with UAVs, given the absence of a human driver behind the steering wheel. However, a challenge in the state-of-the-art technologies for Connected, Cooperative, and Automated Mobility (CCAM), i.e. ITS-G5 (IEEE 802.11p) and Cellular Vehicle-to-Everything (C-V2X), is the lack of a unified communication stack that connects all types of users. This is because the current generation of CCAM communication technologies requires dedicated hardware devices that cannot be easily installed on devices carried by VRUs (such as phones or wearables). This paper aims to address this challenge by providing a real-life, sophisticated solution that offers the CCAM communication stack as a Network-as-a-Service (NaaS) in the 5G and Beyond ecosystem. Integration is achieved by relying on the Service Enabler Architecture Layer (SEAL) principles standardised by the 3rd Generation Partnership Project (3GPP). These architectural principles are embedded in the design of Network-Aware Edge Applications (EdgeApps), which are the building blocks of vertical services in 5G and Beyond. This way, any device or user with the capability to connect to 5G will also be able to retrieve important CCAM services from the network by using EdgeApps. In addition, no dedicated CCAM hardware is needed. Furthermore, this paper provides key lessons learned from the challenges encountered in connecting VRUs and UAVs by integrating CCAM into the 5G and Beyond ecosystem. Moreover, we have conducted real-life experiments to evaluate the system-level latency characteristics of the proposed solution and compared them with those of ITS-G5 and C-V2X.

Connected and Automated Vehicles (CAVs) are revolutionizing the automotive industry by improving real-time situational awareness, and road safety. Connectivity and latency are critical for the secure and efficient operation of CAVs. The evolution of Cellular Vehicular-to-Everything (C-V2X) technology, particularly through Long Term Evolution V2X (LTE-V2X) and its successor New Radio-V2X (NR-V2X), is essential to address these challenges. LTE-V2X and NR-V2X are intended to coexist, complementing each other to cover a broad spectrum of vehicular communication needs. However, network overload is a critical issue, which risks severely degrading the performance of V2X applications and compromising road safety. This study delves into the practical implementation of Network Slicing within a real-world 5G environment, incorporating a modular Open Radio Access Network (O-RAN) architecture on the radio side, and Service-Based Architecture (SBA) principles on the core. We present a Network Slicing configuration that deploys a synergy between the 5G Core (5GC) and the Radio Access Network (RAN). Through strategic placement and policy application across multiple User Plane Functions (UPFs), our configuration enhances network performance and reliability for V2X applications. We validate our approach by demonstrating how this setup effectively manages the high demands of diverse and rigorous applications, ensuring the network requirements for enhanced V2X scenarios under various network conditions. Our results highlight the importance of synergy between 5GC and RAN for the application of an efficient network slicing mechanism in NR-V2X networks.

The purpose of this study was to explore the organizational climate in a women’s prison from the shared perceptions of correctional staff. This study was part of the Prison Research and Innovation Network (PRIN) project, which began in the fall of 2020. Forty-two correctional staff from a low-medium security women’s prison in the Midwest were interviewed in spring 2021. Thematic analysis was conducted to identify staff’s perceptions of organizational climate in the women’s correctional facility. The themes identified as most important to staff were mental health, correctional practices, job satisfaction, and workplace culture. An item pool was developed from the themes identified, and a newly developed organizational climate survey was administered to 80 correctional staff. Qualitative data point to the issues of staff shortages and mandated overtime work impacting the mental health of staff. In addition, organizational climate and its impact on mental health were examined through multiple logistic regressions. The results indicated that having job promotion opportunities, having daily communication between staff and administration, and staff’s knowledge and awareness of correctional policies were positively associated with mental health. This mixed-methods study contributes to understanding the unique challenges correctional staff face working in women’s correctional facilities.

The growing use of DGs presents challenges for system planners and operators, demanding strategic adaptations to accommodate diverse energy sources while ensuring grid stability and operational efficiency. HC analysis has recently been proposed as an essential tool capable of guiding investments into the areas of the network, most likely to offer optimal benefits. This paper presents a method for estimation of photovoltaic HC of the distribution network. For this purpose, the OpenDSS program, employing the Monte Carlo-based method, is utilized to quantify the HC of the electrical distribution network. The simulation is conducted using a real electrical MV network and then verified against the IEEE Test System for validation. This research reports higher HC in comparison with similar methods and models, investigates the influence of constant generation in daily simulation and proves that voltage constraint is violated before line loading. A considerable increase of the circuit losses is recorded if the optimal penetration of PV is exceeded. The contribution of this work is development, testing and implementation of HC estimation method in complex power systems using open-source tools and integrating them in innovative fashion. The results of this research contribute to collective endeavours of energy transition and sustainability.
