Background: Fournier gangrene is an acute and rapidly progressive necrotizing fasciitis of the scrotum, perianal and perineal region of the body. It is a polymicrobial infection having an interplay of both anaerobic and aerobic orgasms in a soup of microbial disaster. Fournier’s gangrene was also initially thought to be an idiopathic condition but a lot of risk factors have been associated now with this condition, both systemic risk factors and local. systemic risk factors include diabetes mellitus, HIV/AIDs, cancers, chronic liver disease, chronic steroid use etc. The local risk factors include perineal injuries, watering can perineum, perianal abscess, chronic perineal itching etc. Purpose: The swiftly flourishing bacteria orgasms cause a similar disruptive event in the body of the patients both clinically and biochemically and these can be used to create a predictive score or index for patients in order to assess the disease severity and guide in the management and prognostication of this condition. Materials and Method: Urology ward record books, clinic record books and operating theater records were used to identify patients managed for Fournier gangrene in ATBUTH Bauchi. A retrospective study of the medical files of all the patients managed from January 2011 to January 2024 was done. Folders were retrieved and the medical records were reviewed. Results: Of the 50 patients reviewed, Male to female ratio is 24:1. The mean age is 56 years (2 weeks to 97 years). Mortality rate was 34%. There is a significant difference between delayed presentation/initial use of unorthodox treatment with mortality (p = 0.002). Of the 17 patients that died, 15 had FGsI > 9 and of the 33 patients that survived 29 had FGsI 9 is 88.2% while the mortality rate for those with FGsI Conclusion: knowledge of the predictors of its mortality is necessary in other to help stratify patients and ensure the best response by the caregivers.

Background: Fournier’s gangrene is a fulminant infection of the genitourinary tract characterized by progressive necrosis of the skin and subcutaneous tissue of the external genitalia. Initially mainly seen involving the scrotum of elderly men with different moods of occurrence each unpleasantly lethal. With varying types of presentation only one thing has remained constant;the poor prognosis of this condition. Purpose/Aim: Thus, it’s important to study the trends of the presentation of this condition laying emphasis on the challenges in the management of these patients;both the negative and positive prognostic factors. Materials and Methods: Urology ward record books, clinic record books and operating theater records were used to identify patients managed for Fournier gangrene in ATBUTH Bauchi. A retrospective study of the medical files of all the patients managed from January 2011 to January 2024 was done. Data was analyzed using sPss version 29. Results: Data from 47 patients seen during the period of study were carefully collected and analyzed. The age range is 2 weeks to 97 years. There were two neonates, one at 2nd week of life and the other at 3rd week. Mortality rate is 36%. The average time duration before presentation for patients that died was two weeks, a minimum of 9 days prior to presentation and a maximum of 21 days, about 10 of which came in septic shock and the remaining presented with fever and very extensive necrotizing fasciitis of the perineum. All the patients that died had diabetes mellitus as a comorbidity except the neonate. All the patients that survived were much younger, all were below 60 years of age (2 weeks - 53 years). Conclusion: Here, we share our experience managing patients with Fournier’s gangrene in our facility in the past 13-year period from January 2011 to January 2024. .

In the digital age, the global character of the Internet has significantly improved our daily lives by providing access to large amounts of knowledge and allowing for seamless connections. However, this enormously interconnected world is not without its risks. Malicious URLs are a powerful menace, masquerading as legitimate links while holding the intent to hack computer systems or steal sensitive personal information. As the sophistication and frequency of cyberattacks increase, identifying bad URLs has emerged as a critical aspect of cybersecurity. This study presents a new approach that enables the average end-user to check URL safety using Microsoft Excel. Using the powerful VirusTotal API for URL inspections, this study creates an Excel add-in that integrates Python and Excel to deliver a seamless, user-friendly interface. Furthermore, the study improves Excel’s capabilities by allowing users to encrypt and decrypt text communications directly in the spreadsheet. Users may easily encrypt their conversations by simply typing a key and the required text into predefined cells, enhancing their personal cybersecurity with a layer of cryptographic secrecy. This strategy democratizes access to advanced cybersecurity solutions, making attentive digital integrity a feature rather than a daunting burden.

The aim of this study of the spatial dispersion of tin, niobium and tantalum mineralization associated with the Mayo Darlé granitoids was to produce prospecting guides through predictive maps of sn, Nb and Ta in the region. It was based on a database (in appendix) obtained after analysis of rock samples (greisens and quartz veins) collected in the field, using a portable X-ray fluorescence (XRF) spectrometer. Two approaches were used: 1) structural studies in the field using the directions of veins and fractures 2) the use of variographic maps, an essential element in geostatistics for determining directional anisotropies. A joint synthesis of the modelling results shows that tin, tantalum and niobium mineralization at Mayo Darlé is concentrated along strike intervals N315E to N320E, with mineralization also occurring along strike N35E for high-grade sn, medium-grade Ta and low-grade Nb. In short, mineral concentrations disperse progressively in space: positively from east to west for tantalum and niobium, and inversely for tin.

One of the most basic and difficult areas of computer vision and image understanding applications is still object detection. Deep neural network models and enhanced object representation have led to significant progress in object detection. This research investigates in greater detail how object detection has changed in the recent years in the deep learning age. We provide an overview of the literature on a range of cutting-edge object identification algorithms and the theoretical underpinnings of these techniques. Deep learning technologies are contributing to substantial innovations in the field of object detection. While Convolutional Neural Networks (CNN) have laid a solid foundation, new models such as You Only Look Once (YOLO) and Vision Transformers (ViTs) have expanded the possibilities even further by providing high accuracy and fast detection in a variety of settings. Even with these developments, integrating CNN, YOLO and ViTs, into a coherent framework still poses challenges with juggling computing demand, speed, and accuracy especially in dynamic contexts. Real-time processing in applications like surveillance and autonomous driving necessitates improvements that take use of each model type’s advantages. The goal of this work is to provide an object detection system that maximizes detection speed and accuracy while decreasing processing requirements by integrating YOLO, CNN, and ViTs. Improving real-time detection performance in changing weather and light exposure circumstances, as well as detecting small or partially obscured objects in crowded cities, are among the goals. We provide a hybrid architecture which leverages CNN for robust feature extraction, YOLO for rapid detection, and ViTs for remarkable global context capture via self-attention techniques. Using an innovative training regimen that prioritizes flexible learning rates and data augmentation procedures, the model is trained on an extensive dataset of urban settings. Compared to solo YOLO,

Microsoft Excel is essential for the End-User Approach (EUA), offering versatility in data organization, analysis, and visualization, as well as widespread accessibility. It fosters collaboration and informed decision-making across diverse domains. Conversely, Python is indispensable for professional programming due to its versatility, readability, extensive libraries, and robust community support. It enables efficient development, advanced data analysis, data mining, and automation, catering to diverse industries and applications. However, one primary issue when using Microsoft Excel with Python libraries is compatibility and interoperability. While Excel is a widely used tool for data storage and analysis, it may not seamlessly integrate with Python libraries, leading to challenges in reading and writing data, especially in complex or large datasets. Additionally, manipulating Excel files with Python may not always preserve formatting or formulas accurately, potentially affecting data integrity. Moreover, dependency on Excel’s graphical user interface (GUI) for automation can limit scalability and reproducibility compared to Python’s scripting capabilities. This paper covers the integration solution of empowering non-programmers to leverage Python’s capabilities within the familiar Excel environment. This enables users to perform advanced data analysis and automation tasks without requiring extensive programming knowledge. Based on soliciting feedback from non-programmers who have tested the integration solution, the case study shows how the solution evaluates the ease of implementation, performance, and compatibility of Python with Excel versions.
