Developing countries are still lagging behind in implementing these principles. This work aims to evaluate the satisfaction of patients operated on and hospitalized in the surgery department at the municipality’s reference health center over a period of 6 months (June 2020 to December 2020). Materials and Methods: This is a quantitative, qualitative, transversal and evaluative study over a period of 6 months based on a self-administered questionnaire to patients who underwent surgery and were hospitalized in the surgery department of the reference health center of commune I upon leaving their hospitalization. The questions are structured around welcome, respect and privacy, care, accommodation conditions as well as overall satisfaction. Results: The survey included 260 patients, 60.8% of whom were male. The 31 - 40 year old age group was in the majority and the majority had completed primary education (42.3%). Married patients were the majority, i.e. 60.4% of cases. Patients were not insured in 66.5% of cases. Almost all of the patients surveyed found that the welcome, care, waiting time, respect and privacy were satisfactory. On the other hand, patients found the rooms and beds uncomfortable. Conclusion: The satisfaction survey reveals worrying data regarding the comfort of patients who must challenge caregivers in healthcare structures. Decision-makers should find useful information there to improve the quality of care.展开更多

Contrast agents mainly cause acute kidney injury through hypoxic damage to renal parenchyma and toxic effects on renal capillaries and tubules. Patients with CI-AKI are more likely to experience adverse events, including longer hospital stay and costs, longer ICU stay, and higher mortality rates. This article elaborates on the definition, epidemiology, risk factors, pathogenesis, and prevention strategies of CI-AKI. Methods: We conducted an extensive literature search using contrast agents and AKI as keywords to identify relevant studies on CI-AKI. Conclusion: CI-AKI is a significant clinical challenge that requires a multifaceted approach to prevention and management. Understanding the risk factors, pathophysiology, and current best practices is essential for healthcare providers to optimize patient care and improve outcomes in those undergoing contrast-enhanced imaging procedures. Hydration therapy is currently the main prevention method, but antioxidants may also become a new strategy.展开更多

This paper presents Sher, a Python-based tool that enhances the security of GitHub Actions by automating the detection and remediation of security issues in workflows. Self-Hosted Ephemeral Runner, or Sher, acts as a broker between GitHub’s APIs and a customizable, isolated environment, analyzing workflows through a static rules engine and automatically fixing identified issues. By providing a secure, ephemeral runner environment and a dynamic analysis tool, Sher addresses common misconfigurations and vulnerabilities, contributing to the resilience and integrity of DevSecOps practices within software development pipelines.展开更多
