Does Ruxolitinib, in Comparison to Best Available Therapy (BAT), Improve Pruritis Symptoms in Patients with Polycythemia Vera?

引用

Journal of Biosciences and Medicines 2024年第3期12卷 35-43页

作者： Zachary samuel Thorogood Philadelphia College of Osteopathic Medicine Philadelphia USA

Polycythemia vera manifests as a myeloproliferative neoplasm associated with diverse symptoms, including aquagenic pruritis. This systematic review addresses the pressing need to enhance the understanding of the disease’s symptomatology and optimize treatment strategies for improved patient outcomes. The rarity and low prevalence of polycythemia vera underscore the importance of this investigation, as existing standard of care involves a multifaceted approach and significant healthcare costs. Despite advancement in therapeutic options, persistent symptoms and resistance to first-line treatments pose challenges. Ruxolitinib has emerged as a promising intervention, demonstrating clinically significant improvement for patients. This systematic review appraises three randomized controlled trials, shedding light on the efficacy of ruxolitinib and its potential to ameliorate pruritis symptoms in symptomatic patients.

The Kandi basin is located in northeast Benin (West Africa). This study is focused on the estimation of water fluxes exchanged between the river Niger (and its tributaries) and the transboundary Iullemeden Aquifer System. In that framework, an innovative approach based on the application of the Bayesian Mixing Model (MixSIAR) analysis on water isotopes (oxygen-18, deuterium and tritium) was performed. Moreover, to assess the relevance of the model outputs, Pearson’s correlation and Principal Component Analysis (PCA) have been done. A complex relationship between surface water and groundwater has been found. Sixty percent (60%) of groundwater samples are made of more than 70% river water and rainwater;while 31.25% of surface water samples are made of about 84% groundwater. To safeguard sustainable water resources for the well-being of the local communities, surface water and groundwater must be managed as a unique component in the Kandi basin.

Open Journal of Applied Sciences 2024年第9期14卷 2519-2543页

作者： samuel Lungu Mayumbo Nyirenda Department of Computer Studies University of Zambia Lusaka Zambia

In the evolving landscape of software engineering, Microservice Architecture (MSA) has emerged as a transformative approach, facilitating enhanced scalability, agility, and independent service deployment. This systematic literature review (SLR) explores the current state of distributed transaction management within MSA, focusing on the unique challenges, strategies, and technologies utilized in this domain. By synthesizing findings from 16 primary studies selected based on rigorous criteria, the review identifies key trends and best practices for maintaining data consistency and integrity across microservices. This SLR provides a comprehensive understanding of the complexities associated with distributed transactions in MSA, offering actionable insights and potential research directions for software architects, developers, and researchers.
