Relationship between admission criteria and academic performance in basic science courses in health science colleges in KAU.

BACKGROUND: At King Abdulaziz University, medical and health science schools depend on admission exams (aptitude and achievement) and preparatory year scores in their students' selection. However, with the growing number of applicants and the drastic changes in teaching and assessment in these colleges, continuous assessment and development of admission criteria are needed. In this study, we aimed to evaluate the correlation of admission exam scores, in addition to the preparatory year Grade Point Average (GPA), with academic performance in the basic science subjects such as Clinical Biochemistry and Clinical Pharmacology in health science colleges. METHODS: The study was conducted on four cohort studies, two faculty of nursing cohorts; nursing students (2017-2018, n=146) nursing students (2018-2019, n=81), and two faculty of applied medical sciences cohorts, clinical nutrition students (2017-2018, n=33), and clinical nutrition students (2018-2019, n=28). The students' scores of General Aptitude Test (GAT), Scholastic Achievement Admission Test (SAAT), and preparatory year GPA were all recorded at the beginning of each semester before the beginning of courses. Clinical Biochemistry and Clinical Pharmacology exam results were recorded at the end of the semester. Correlation was done for each cohort and all cohorts pooled. RESULTS: Results showed only a weak correlation detected between SAAT and the overall achievement in Clinical Biochemistry (r= 0.192, P= 0.042) in nursing students (2017-2018), but no correlation was seen with SAAT or preparatory year scores. There was also no significant correlation between admission exams scores and the students' academic achievement in Clinical Biochemistry or Clinical Pharmacology. On the other hand Clinical Pharmacology exam results showed a significant positive correlation with Clinical Biochemistry results (r=0.688, P=0.000). CONCLUSION: Our results could indicate the need to revisit the admission criteria for these colleges. Furthermore, specific preparatory year tracks for health science colleges can ensure that students improve the specific skills and knowledge required for their future college years3.

Factors Involved in Relapse of Multiple Sclerosis.

Multiple sclerosis (MS), a chronic autoimmune disorder, affects the central nervous system (CNS). It affects the brain, spinal cord, and optic nerve, leading to problems with vision, balance, muscle control, and other basic bodily functions. MS relapse (MSR) involves an acute inflammatory demyelinating reaction within the CNS. This review focuses on the main factors involved in MSR based on a detailed literature search. Evidence suggests that MSR is influenced by age, sex, pregnancy, serum levels of Vitamin D, interactions between genetic and environmental factors, and infectious diseases. Many of these factors are modifiable and require the attention of patients and health-care providers if favorable outcomes are to be realized. Identification of MSR risk factors can help in the development of therapies that could be used to manage MS and MSR.
