Staphylococcus aureus is a pathogenic bacterium that can evolve rapidly to methicillin-resistant Staphylococcus aureus (MRSA). MRSA is a global health concern that is associated with significant morbidity and mortality. This study was to determine the prevalence and Associated Risk Factors of staphylococcus aureus and MRSA isolates obtained from patients seeking treatment in Nakuru County Referral and Teaching Hospital. A descriptive cross-section study design was used with a laboratory experimental component and it was carried out in Nakuru County Referral and Teaching Hospital, Kenya. A total of 354 laboratory samples were randomly collected from different laboratory samples/sites: blood, urine, wound, nasal swabs, pus, tissue, abscess, sputum, ear swabs, as well as cerebrospinal fluid (CSF) culture, skin swabs and synovial fluid culture over a period of six months. These samples were tested for presence of staphylococcus aureus and MRSA isolates using Culture methods and Antibiotic Sensitivity Tests. The study analyzed 354 participants, with a median age of 35 years. Most participants (56.7%) were from medical wards, 20.4% from outpatient clinics, and 11% from Diabetic Care Centre. Staphylococcus aureus was found in 7.1% of samples, with MRSA present in 2.3%. Other isolated organisms included Coagulase Negative Staphylococci (7.1%), E. coli (6.8%), Proteus spp. (5.1%), and Pseudomonas spp. (5.9%). The prevalence of MRSA among the participants is low.

The research article investigates an ever-evolving knowledge mapping of ransomware using the CiteSpace Visualization tool. The foundation for this research is the body of scientific literature on ransomware that was extracted between 2013 and 2023 from the Web of Science Core Collection database. The study methodology is a five-step procedure that follows a systematic approach from data collection to bibliometric analysis using Citespace, identifying hot research topics, analyzing the results, and offering future research paths. It provides cited reference analysis, author and country cooperation networks and co-citation networks, institution collaboration networks, annual publishing patterns, and journal co-citation analysis. Using keyword co-occurrence analysis, it also provides information about hot research topics and emerging trends that pertain to ransomware. The findings identify the most influential authors, countries, and institutions that have actively contributed to ransomware research. The current study also identifies emerging trends and hot research topics, thus providing future research directions in these areas. Ransomware is a highly sophisticated type of malware that has become a dynamic threat to the cyberspace during the last ten years. Technological and IT infrastructure developments have increased the attack surface. The capability of ransomware to wreak havoc in cyberspace has made it a persistent danger. Therefore, it is essential to carry out comprehensive research using scientometric analysis to address the worldwide landscape of ransomware and provide insights into its current situation.
