The digital transformation of global commerce has fundamentally altered the landscape of tax administration, presenting unprecedented challenges for tax authorities worldwide. This comprehensive review examines the transformative potential of blockchain technology in revolutionizing tax compliance and enhancing transparency in global transactions. Through systematic analysis of existing literature, case studies, and implementation frameworks, we investigate how blockchain's core attributes of immutability, traceability, and decentralization can address critical challenges in contemporary tax administration. The review synthesizes evidence from multiple jurisdictions, demonstrating blockchain's capacity to reduce tax fraud, streamline compliance processes, and facilitate real time tax collection. Our analysis reveals that blockchain implementation in tax systems can potentially reduce tax gaps by 75-80% in VAT schemes and decrease compliance costs by 40-50% for businesses operating across multiple jurisdictions. The paper also explores critical challenges, including scalability issues, regulatory frameworks, and implementation barriers, providing a balanced perspective on both opportunities and limitations. Furthermore, we examine emerging trends in blockchain based tax solutions, including smart contracts for automated compliance, cross border information sharing protocols, and real time reporting frameworks. This review contributes to the growing body of literature on digital transformation in tax administration by offering a comprehensive framework for understanding blockchain's role in creating more efficient, transparent, and equitable tax systems. Our findings suggest that while blockchain technology presents promising solutions for tax administration challenges, successful implementation requires careful consideration of technical infrastructure, legal frameworks, and international cooperation mechanisms.

A 28-day sub-acute study used 120-140 g Wistar rats. Three groups of six (n=6) rats were assembled. Group A (control) received feed and water, group B received 500 mg/kg of reddish potash (natron) while group C received 500 mg/kg of greyish potash (trona). Standard methods were used in analyzing parameters. Data was analyzed with SPSS, version 27. Results were shown as mean ± SD. One-way ANOVA was performed to compare mean values. Hematological results in groups A and B reveal a significant (p<0.05) decrease in red blood cells and platelets and an increase in white blood cells (p<0.05) compared to the control. The electrolytes results recorded significant increase(p<0.05) in Na+ in group B while group C recorded a significant increase in K+ and CL- when compared to the control. Group B had a significantly higher creatinine and urea than group C and the control. The study revealed a significant increase (p<0.05) in total cholesterol and high density lipoprotein in group B, but not in triglycerides or low density lipoprotein. The study concludes that on chronic consumption, low dosages (10 % of LD50) of natron or trona can alter hematological parameters, electrolyte balance, renal function (particularly in natron), and lipid profile.

Enterococci are Gram-positive bacteria that inhabit the gastrointestinal tract of many organisms, including humans. These bacteria can easily adapt to their surrounding environment, even under stress conditions that can be lethal to other microorganisms. Among the species described in this genus, faecalis and faecium stand out, considered one of the main causes of nosocomial infections due to their ability to adapt and resist in clinical environments. They are recognized as opportunistic pathogens that can cause a variety of serious infections, such as endocarditis, urinary tract infections, and bacteremia, especially in immunocompromised patients or those with invasive medical devices. Recently, it has been observed that Enterococcus presents an increase in resistance to antibiotics, heavy metals, as well as external environmental conditions such as heat and desiccation. This resistance has been directly related to the capacity to form biofilm, an organized microbial ecosystem that makes it almost impermeable and serves as a shield for the bacteria. In addition, biofilm has been linked to bacterial virulence due to the presence of virulence factors. Therefore, researchers are interested in conducting research on the correlation between biofilm formation, virulence factors and antimicrobial resistance, which is essential to understanding the pathogenesis of these infections and improving treatment strategies.

This study investigates the essential role of operational oversight in managing high-stakes turnaround situations, with a particular focus on C-suite leadership's strategic, financial, and operational responses to critical organizational challenges. Utilizing a comprehensive review of current literature and analysis of case studies, the research explores the foundational components of oversight—including accountability, resource allocation, and performance monitoring—that underpin effective turnaround efforts. The findings reveal that successful turnarounds hinge on adaptive oversight structures, which allow leaders to respond agilely to fluctuating market demands and operational complexities, thus ensuring alignment with long-term recovery goals. Advanced technologies, such as predictive analytics and AI-driven risk management tools, are highlighted as transformative in enhancing oversight capabilities, enabling C-suite leaders to implement data-driven decision-making processes and real-time monitoring. Furthermore, the study emphasizes the necessity of robust governance frameworks and transparent communication channels to foster stakeholder trust, which is critical for maintaining morale and securing resources during recovery. The study concludes that a multidimensional approach—integrating technological, strategic, and governance-driven oversight—enhances resilience in turnaround situations, positioning organizations for sustainable growth. Recommendations include adopting agile oversight frameworks, prioritizing environmental, social, and governance (ESG) principles, and fostering a culture of continuous improvement and adaptability within the organization. These strategies equip leaders with the tools and insights needed to navigate the complexities of high-stakes turnarounds effectively, thereby contributing to organizational stability and future success.

Background: Chemotherapy poses significant occupational hazards to healthcare professionals, particularly nurses, with exposure to cytotoxic drugs linked to severe health consequences such as cancer, infertility, and miscarriages. This review examines factors influencing safe chemotherapy handling and identifies strategies to minimize exposure risks.
Methods: A comprehensive literature search was conducted using databases and keywords like "chemotherapy," "safe handling," "hazardous drugs," and "nurses." Studies on individual and organizational factors influencing safe practices were included, while review articles and theses were excluded. The findings from multiple sources were synthesized to highlight key strategies for improving chemotherapy safety.
Results: Individual factors affecting safe handling include knowledge of chemotherapy hazards, self-efficacy in using personal protective equipment (PPE), and perceived risk of exposure. Organizational factors include workplace safety climate, clear policies and procedures, availability of PPE, workload, staffing ratios, managerial support, and comprehensive training programs.
Conclusion: Ensuring safe chemotherapy handling requires a multi-faceted approach addressing both individual and organizational factors. Key strategies include enhancing knowledge through education, promoting self-efficacy, fostering a positive safety climate, developing clear policies, ensuring adequate resources, optimizing staffing, providing managerial support, and implementing continuous training programs to improve safe practices.

Background: One of the most common diseases in gynecology, abnormal uterine bleeding (AUB) has a major negative impact on women's quality of life. Unusual bleeding in women can be brought on by thyroid conditions. The purpose of the study is to determine how common thyroid abnormalities are in women who have irregular uterine bleeding. It also looks at the menstrual patterns linked to thyroid disorders. The study concluded that hypothyroidism patients have menorrhagia, hyperthyroidism patients may experience dysmenorrhea, and thyroid dysfunction may result in irregular uterine hemorrhage.
Materials and procedures: Premenopausal women with abnormal uterine bleeding (AUB) participated in a prospective observational study conducted in the gynecology department of a tertiary care hospital in Trivandrum between November 2022 and April 2023 (a period of six months).
Result: Of the 75 patients who were chosen, 71 (94.7%) had AUB-induced hypothyroidism and 4 (5.3%) had AUB-induced hyperthyroidism. Regarding the menstrual pattern, 83.1% of patients with hypothyroidism and 100% of patients with hyperthyroidism reported experiencing menorrhagia or dysmenorrhea.
The study concludes that there is a considerable correlation between thyroid issues and abnormal uterine hemorrhage. The majority of female AUB patients exhibit both hyperthyroidism and hypothyroidism. The most common menstrual pattern linked to hypothyroidism was menorrhagia. Dysmenorrhea was thought to be the most prevalent monthly abnormality in hyperthyroidism.
