Objective: The objective of this study was to describe medical students’ learning styles and locus of control (LOC) and to determine their association with academic achievement. Methods: A cross-sectional study was performed at a health science university in Saudi Arabia. A sample of 158 medical students completed Kolb’s learning style and locus of control scales. The authors measured academic achievement by grade point average (GPA) and collected demographic characteristics. Results: Most students’ learning styles were classified as convergent (51.3%), whereas the rest adopted divergent (23.4%), accommodative (18.4%), and assimilative (7%) styles. Analysis revealed that students with a lower LOC tend to have higher GPAs than those with a higher LOC. However, no association was found between Kolb’s learning styles and LOC or GPA. Conclusions: The findings of this study provide educators with essential insights into factors that enhance students’ academic achievements. We conclude that locus of control plays a crucial role in academic success. Medical educators should consider diverse student learning styles to adopt appropriate teaching methods that meet students’ needs, ultimately improving educational practices and outcomes in medical education.

Antibiotic resistance to Klebsiella pneumoniae poses a major public health threat, particularly in intensive care unit (ICU) settings. The emergence of extensively drug-resistant (XDR) strains complicates treatment options, requiring a deeper understanding of their genetic makeup and potential therapeutic targets. This research delineated an extensively drug-resistant (XDR) Klebsiella pneumoniae strain obtained from an ICU patient and telomeric temperate phage derived from hospital effluent. The bacteria showed strong resistance to multiple antibiotics, including penicillin (≥16 μg/mL), ceftriaxone (≥32 μg/mL), and meropenem (≥8 μg/mL), which was caused by SHV-11 beta-lactamase, NDM-1 carbapenemase, and porin mutations (OmpK37, MdtQ). The strain was categorized as K46 and O2a types and carried virulence genes involved in iron acquisition, adhesion, and immune evasion, as well as plasmids (IncHI1B_1_pNDM-MAR, IncFIB) and eleven prophage regions, reflecting its genetic adaptability and resistance dissemination. The 172,025 bp linear genome and 46.3% GC content of the N-15-like phage showed strong genomic similarities to phages of the Sugarlandvirus genus, especially those that infect K. pneumoniae. There were structural proteins (11.8%), DNA replication and repair enzymes (9.3%), and a toxin–antitoxin system (0.4%) encoded by the phage genome. A protelomerase and ParA/B partitioning proteins indicate that the phage is replicating and maintaining itself in a manner similar to the N15 phage, which is renowned for maintaining a linear plasmid prophage throughout lysogeny. Understanding the dynamics of antibiotic resistance and pathogen development requires knowledge of phages like this one, which are known for their temperate nature and their function in altering bacterial virulence and resistance profiles. The regulatory and structural proteins of the phage also provide a model for research into the biology of temperate phages and their effects on microbial communities. The importance of temperate phages in bacterial genomes and their function in the larger framework of microbial ecology and evolution is emphasized in this research.
