BACKGROUND After introducing interleukin(IL)-1/IL-6 inhibitors, some Still and Still-like patients developed unusual often fatal pulmonary disease. This complication was associated with scoring as DReSS (drug reaction with eosinophilia and systemic symptoms) implicating these inhibitors, although DReSS can be difficult to recognize in the setting of systemic inflammatory disease. OBJECTIVE We sought to facilitate recognition of IL-1/IL-6 inhibitor-DReSS in systemic inflammatory illnesses (Still/Still-like) by looking at timing and reaction-associated features. We evaluated outcomes of stopping or not-stopping IL-1/IL-6-inhibitors after DReSS reaction began. METHODS In an international study collaborating primarily with pediatric specialists, we characterized features of 89 drug-reaction cases versus 773 drug-exposed controls and compared outcomes of 52 cases stopping IL-1/IL-6-inhibitors to 37 cases not-stopping these drugs. RESULTS Before reaction began, drug-reaction cases and controls were clinically comparable, except for younger disease onset age for reaction cases with pre-existing cardiothoracic comorbidities. After reaction began, increased rates of pulmonary complications and macrophage activation syndrome (MAS), differentiated drug-reaction cases from drug-tolerant controls (p=4.7x10-35; p=1.1x10-24, respectively). Initial DReSS feature was typically reported 2-8 weeks after initiating IL-1/IL-6-inhibition. In drug-reaction cases stopping versus not-stopping IL-1/IL-6-inhibitor treatment, reaction related features were indistinguishable, including pulmonary complication rates [75%(39/52] versus [76%(28/37)]. Those stopping subsequently required fewer medications for treatment of systemic inflammation, had decreased rates of MAS, and improved survival (p=0.005, multivariate regression). Resolution of pulmonary complications occurred in 67%(26/39) of drug-reaction cases who stopped and in none who continued inhibitors. CONCLUSIONS In systemic inflammatory illnesses, recognition of IL-1/IL-6-inhibitor-associated reactions followed by avoidance of IL-1/IL-6-inhibitors significantly improved outcomes.

The targeted compounds in this research, resveratrol analogs 1–14, were synthesized as mixtures of isomers by the Wittig reaction using heterocyclic triphenylphosphonium salts and various benzaldehydes. The planned compounds were those possessing the trans-configuration as the biologically active trans-resveratrol. The pure isomers were obtained by repeated column chromatography in various isolated yields depending on the heteroaromatic ring. It was found that butyrylcholinesterase (BChE) was more sensitive to the heteroaromatic resveratrol analogs than acetylcholinesterase (AChE), except for 6, the methylated thiophene derivative with chlorine, which showed equal inhibition toward both enzymes. Compounds 5 and 8 achieved the highest BChE inhibition with IC50 values of 22.9 and 24.8 μM, respectively. The same as with AChE and BChE, methylated thiophene subunits of resveratrol analogs showed better enzyme inhibition than unmethylated ones. Two antioxidant spectrophotometric methods, DPPH and CUPRAC, were applied to determine the antioxidant potential of new heteroaromatic resveratrol analogs. The molecular docking of these compounds was conducted to visualize the ligand-active site complexes’ structure and identify the non-covalent interactions responsible for the complex’s stability, which influence the inhibitory potential. As ADME properties are crucial in developing drug product formulations, they have also been addressed in this work. The potential genotoxicity is evaluated by in silico studies for all compounds synthesized.

Abstract Let S be a groupoid (magma) with zero 0, and let R=⊕s∈SRs be a contracted S-graded ring, that is, an S-graded ring with R0=0. By G(HR) we denote the undirected power graph of a multiplicative subsemigroup HR=∪s∈SRs of R, and by G*(HR)a graph obtained from G(HR) by removing 0 and its incident edges. If Re is a nonzero ring component of R, then G*(Re) denotes a subgraph of G*(HR), induced by Re*. In this paper we address a problem raised in [Abawajy, J., Kelarev, A., Chowdhury, M.: Power Graphs: A Survey. Electron. J. Graph Theory Appl. 1(2), 125–147 (2013)]. Namely, let S be torsion-free, that is, sn=tn implies s = t for all s, t∈S, and all positive integers n, and let S be 0-cancellative, that is, for all s, t, u∈S,su=tu≠0 implies s=t, and us=ut≠0 implies s=t. Also, let R be semisimple Artinian. We prove that if G*(Re) is connected for every nonzero ring component Re of R, then the connected components of G*(HR) are precisely the graphs G*(Re).

Artificial intelligence, Machine Learning, and Deep Learning are increasingly making significant contributions to the field of medicine. Individual patient conditions, disease localization, and various influencing factors underscore the complexity of disease diagnosis and treatment planning. Introducing new technologies can revolutionize medical diagnostics, facilitating swift and accurate assessments. Among the noninvasive diagnostic methods, Magnetic Resonance Imaging (MRI) stands out, particularly in tumor diagnosis. UNet, renowned for its effectiveness in medical image analysis, serves as a robust model for semantic segmentation, as does DeepLabV3+. However, these models are inherently complex, and their inference process can be time-consuming. By leveraging the OpenVINO toolkit, the inference process is significantly reduced. In this study, nearly a 2-fold acceleration is achieved in inference time with the DeepLabV3+ model and a roughly 1.2-fold improvement with the UNet model on CPU. Moreover, when employing GPU with FP16 precision, the acceleration reached almost 2.5fold for UNet and nearly 3-fold for DeepLabV3+, showcasing the substantial performance enhancements attainable through optimized hardware utilization.

This research explores into the utilization of synthetic data within image classification tasks and evaluates its efficiency in comparison to the utilization of real data. To facilitate this investigation, we employ the CIFAKE dataset, comprising the well-established CIFAR10 dataset and an equivalent number of images synthetically generated using the Latent Diffusion Model (LDM). The increasing demand for diverse and abundant labeled datasets has prompted the emergence of synthetic data as a potential solution to address data scarcity. Within this study, we scrutinize the performance of image classification models trained on both real and synthetic datasets. To ensure a comprehensive evaluation, we alternately apply test data across different models. Our analysis encompasses diverse factors, including classification accuracy, generalization capabilities, and robustness in various scenarios. The findings provide valuable insights into the efficacy of synthetic data as a viable alternative or complement to real data in the realm of image classification.

Noise removal in image processing and computer vision is a crucial preprocessing step employing a spectrum of techniques. In recent years, autoencoders exhibit remarkable efficacy in mapping noisy images to clean counterparts, capturing intricate relationships for effective noise removal. Motivated by the challenges posed by noise in real-world images, this research focuses on the denoising preprocessing step, crucial for tasks like object detection and segmentation. The study explores the application of autoencoders in removing artificially added noise from images within the MNIST dataset. The MNIST dataset’s simplicity and historical significance facilitate focused examinations on specific aspects, such as the impact of different types and levels of noise. The efficacy of autoencoders for noise removal is assessed through the evaluation of results using various metrics, including SSIM, PSNR, MSE, and RMSE. In one remarkable instance, the reconstruction process achieved an impressive peak SSIM score of 99.06%, showcasing the efficacy of the method in preserving image fidelity despite the challenging presence of noise. This comprehensive analysis provides valuable insights into the performance and effectiveness of autoencoders in the context of noise reduction in various domains.

Background/Objectives: The aim of this study was to evaluate brain metabolism using MR spectroscopy (MRS) after recovery from Coronavirus disease (COVID-19) and to test the impact of disease severity on brain metabolites. Methods: We performed MRS on 81 individuals (45 males, 36 females, aged 40–60), who had normal MRI findings and had recovered from COVID-19, classifying them into mild (17), moderate (36), and severe (28) groups based on disease severity during the acute phase. The study employed two-dimensional spectroscopic imaging above the corpus callosum, focusing on choline (Cho), creatine (Cr), and N-acetylaspartate (NAA). We analyzed Cho/Cr and NAA/Cr ratios as well as absolute concentrations using water as an internal reference. Results: Results indicated that the Cho/Cr ratio was higher with increasing disease severity, while absolute Cho and NAA/Cr ratios showed no significant differences across the groups. Notably, absolute Cr and NAA levels were significantly lower in patients with severe disease. Conclusions: These findings suggest that the severity of COVID-19 during the acute phase is associated with significant changes in brain metabolism, marked by an increase in Cho/Cr ratios and a reduction in Cr and NAA levels, reflecting substantial metabolic alterations post-recovery.

Introduction. Although inguinal hernia surgery is the most common surgical procedure worldwide, the best surgical method is still not universally accepted. The Lichtenstein technique is considered the gold standard, although it also has its limitations. Therefore, there is still a need for new techniques, such as the Desarda technique. The aim of this article is to evaluate and compare the postoperative morbidity of two tension-free techniques for inguinal canal pla-stic surgery with and without the use of mesh. Methods. This prospective randomized clinical study was conducted at the Clinic for General and Abdominal Surgery of the Clinical Center of the University of Sarajevo from January 2017 to December 2022. The study included 60 patients with primary inguinal hernia who met the predefi ned inclusion and exclusion criteria and were randomly allocated into two equal groups: 30 patients operated on by the Desarda technique and 30 patients operated on by the Lichten-stein technique. Results: The following parameters showed a statistically signifi cant diff erence in favor of the Desarda operative technique: shorter hospitalization, lower level of postoperative pain, faster achievement of early physical activity, lesser amount of analgesic consumption, earlier return to regular daily and work activities, and absence of chronic inguinal pain. Postoperative morbidity was more frequent in the Lichtenstein group, but likely due to the small sample size, this diff e-rence remained statistically insignifi cant. Conclusion: Patients operated on by the Desarda method exhibited signifi cantly lower levels and frequencies of postoperative pain, faster postoperative recovery, and return to usual daily and work activities.

Prostate cancer (PC) is one of the most commonly diagnosed malignancies worldwide and the second leading cause of mortality among men (1). Nowadays, radical prostatectomy is considered the primary therapeutic modality for treating patients with localized PC (stage pT2), providing a five-year survival rate of nearly 100% (2). Sexual dysfunction in men associated with PC treatment encompasses three distinct entities: erectile dysfunction (ED) and penile shortening; ejaculatory and orgasmic dysfunction; and psychosexual dysfunction, which pertains to sexual desire, intimacy, and mental health (3). Penile rehabilitation (PR) is defined as the use of any intervention or combination of procedures aimed not only at achieving an erection sufficient for satisfactory sexual intercourse but also at restoring erectile function to its preoperative level (4). Despite eff orts to preserve the neurovascular bundle during radical prostatectomy, ED remains a common outcome. Although prevalence rates of ED after the procedure vary widely, recent studies report rates as high as 85% (5). This is primarily due to the lack of control over factors that significantly influence the erection recovery, such as the patient’s age, preoperative erectile function, comorbidities, surgical approach (open, laparoscopic, or robot-assisted), surgical technique (non-, uni-, or bilateral nerve-sparing), and the surgeon’s skills and experience. The pathophysiology of postoperative ED is multifactorial. The primary mechanisms are believed to be damage to the cavernous nerves, whether through dis-section or neuropraxia, and vascular injury, which includes damage to the accessory pudendal arteries, hypoxia and fibrosis of the endothelium and smooth muscle, resulting in penile shortening (6-8). Although there is no consensus on the optimal approach to PR, accepted modalities include the use of phosphodiesterase type 5 inhibitors (PDE-5i; such as sildenafil, vardenafil, tadalafil) and vacuum erection de-vices (VED) or vacuum constriction devices (VCD) as first-line therapies. Second-line treatments involve prostaglandin E1 preparations for intracavernous, or intraurethral (MUSE – “Medicated Urethral System for Erection”) administration. The final therapeutic option is the implantation of penile prostheses (3-10).

This paper aims to examine the awareness and perceptions of depositors in Bosnia and Herzegovina regarding the features of investment deposits in Islamic finance. It evaluates the contribution of mudarabah-based deposits to the financial inclusion of Muslims and identifies factors influencing clients' decisions to place their funds in Islamic banks. The study employs a quantitative research methodology, utilizing an online survey distributed via LimeSurvey to collect primary data. The survey targeted bank clients in Bosnia and Herzegovina, and a non-random convenience sample was obtained by promoting the survey link on a Facebook page aimed at users in the region. Paid advertising was used to enhance visibility, and direct outreach was conducted in cities with Islamic bank branches to ensure a representative sample. The survey included questions on demographic information, awareness of investment deposits, understanding of Islamic finance, and attitudes towards banking risks and returns. The structured nature of the survey allowed for effective data collection and analysis to identify knowledge gaps and depositor attitudes. The findings reveal that a significant portion of respondents lack adequate knowledge about investment deposits, posing a critical barrier to their effective use for mobilizing savings and enhancing financial inclusion. Muslim clients identify interest as a significant hurdle to saving in conventional banks, with similar expectations and risk aversion observed in Islamic banking investment accounts. This research underscores the potential role of investment deposits in advancing financial inclusion by addressing knowledge gaps and examining factors influencing clients' decision-making processes. It highlights the need for increased awareness and education about investment deposits to facilitate their wider adoption among depositors, enhancing the understanding of leveraging Islamic finance principles to promote financial inclusion and meet the unique needs of Islamic savers and investors in Bosnia and Herzegovina.
