Comparison of serum anti-mullerian hormone among fertile and infertile normal and diminished ovarian reserve groups.

OBJECTIVE: To compare anti-mullerian hormone among fertile and infertile groups of women in their reproductive age. METHODS: This case-control study was conducted at the Dow University of Health Sciences in collaboration with Civil Hospital, Karachi, from October 2011 to October 2012, and comprised fertile non-pregnant and infertile women. Serum anti-mullerian hormone levels were measured in both the infertile and fertile groups. Blood samples to determine anti-mullerian hormone levels were obtained irrespective of their menstrual cycle days. Infertile cases were further divided into two subgroups according to serum anti-mullerian hormone levels, into normal ovarian reserve group and diminished ovarian reserve group. SPSS 18 was used for data analysis. RESULTS: Of the 100 participants, 48(48%) women were fertile controls and 52(52%) were infertile. Of the latter, there were 30(57.69%) in the normal ovarian reserve group and 22(42.31%) in the diminished ovarian reserve group. The mean age of the participants was 26±4.026 years (range: 25-35 years). The mean values for the control, normal ovarian reserve and diminished ovarian reserve groups were 1.9±0.16 ng/ml, 0.89±0.47 ng/ml and 2.0±0.6 ng/ml, respectively (p=0.001). CONCLUSIONS: Mean concentration of serum anti-mullerian hormone in infertile women with diminished ovarian reserve was significantly lower than that in normal ovarian reserve group and fertile control women.

Impacts of Changing the Curriculum Design on the Examination Results of Anatomy and Physiology Course.

Introduction Innovating strategies have become a compulsion in all fields associated with improved outcomes. Similarly, an innovation was introduced in the curriculum design and content to be tested for the Anatomy and Physiology course at the College of Science and Health Professions (COSHP), King Saud Bin Abdulaziz University for Health Sciences (KSAU-HS), in the spring semester of 2020. Before the COVID-19 pandemic, until the spring semester of 2019, two examinations were conducted as continuous assessments (Midterm I and II), followed by a comprehensive Final examination. In the spring semester of 2020, these examinations were replaced with Block I, II, and III examinations, respectively, with modified content and weightage. The Final examination was comprehensive and included 24 Anatomy, 21 Physiology lectures, and three case-based learning (CBL) sessions, whereas Block III included only eight Anatomy, seven Physiology lectures, and 1 CBL session. Midterm I and II weighed 20% each with a comprehensive examination of 35%, while Block I, II, and III were all 25% each. This study focuses on the impact of the curriculum modifications on the results of written examinations for preprofessional students enrolled at Riyadh, Jeddah, and Al-Ahsa campuses. Methods This retrospective study included data from 2356 male and female students from Riyadh, Jeddah, and Al-Ahsa. Data included Midterm I and II grades and Final examination grades for spring semester 2019 and Block I, II, and III examination grades for spring semester 2021. The results of the spring semester 2021 examinations were compared with the spring semester 2019 examination. The spring semester of 2020 was skipped to avoid the effect of online examinations during the COVID-19 restriction period. Data were analyzed using the statistical software SPSS version 23.0 (IBM Corporation, Armonk, NY, USA). Coefficient of variation (CV) compared spring semester 2019 and spring semester 2021 examination outcomes. The findings were analyzed concerning data related to gender, student groups, and campuses. An independent t-test of proportion was used to compare the CVs for spring 2019 and 2021. Results The overall comparison showed better results in the spring semester of 2021 (p-value < 0.01). Campus-wise, the results were significantly better for Riyadh (p-value < 0.01). The gender-wise study showed better performance from male students (p-value < 0.01). Concerning campus and gender, the results of male and female students of the Riyadh campus came out to be highly significant (p-value < 0.01). Conclusions Changing from Midterms to the Block system significantly improved the Block III examination results in spring semester 2021, particularly at the Riyadh campus. Overall, the changes remained helpful to all students. Further studies are needed to investigate the long-term effect of the curriculum changes.

Potential Utility of Cell Free High Mobility Group AT-hook 2 (HMGA2) as a Prognostic Biomarker in Liquid Biopsies of Oral Squamous Cell Carcinoma.

BACKGROUND: Locoregional spread is a frequent finding in oral cancer which dictates poor prognosis. HMGA2 expression has been linked to malignant traits of oral cancer in tissue biopsies however, data on HMGA2 expression in liquid biopsies in oral cancer is sparse. Purpose of this study was to explore prognostic relevance of HMGA2 in liquid biopsies of oral cancer patients. PATIENTS AND METHODS: After obtaining approval from Institutional Review Board of Ziauddin University and informed written consent from study subjects, expression of circulating HMGA2 was evaluated in 96 OSCC cases and 100 age and sex matched controls via real time PCR using specific set of primers. We further analyzed relationship of various sociodemographic and clinicopathological variables with HMGA2expression and explored its prognostic potential. RESULTS: Expression was seen in 22 (23%) cases. A higher expression was observed among subjects with local invasion (52.6% vs 47.4 %), distant metastasis (71.4% vs 28.6%) and tumor recurrence (57.1% vs 42.9%) p.

Assessing the Effects of Basic Medical Science Courses on the Knowledge and Attitude towards Antibiotic Usage among Pre-Professional Students in Saudi Arabia.

The curriculum of medical schools includes courses on antibiotics. Therefore, it is worth exploring information related to the knowledge and attitudes about antibiotics. In this cross-sectional study the questionnaire was administered to the undergraduates in two phases, before and after attending the basic medical science courses. The data were collected on demographic variables, source of antibiotics, level of knowledge, and changes in attitude statements. Data analysis was implemented using SPSS. The mean age of participants was 19.87 and 20.15 in phases I and II, respectively. Most of the participants' parents had education at the university level and a monthly income above 15,000 SAR. Generally, students had good knowledge and attitude about antibiotics. A significant improvement in students' knowledge in phase-II was noticed in "level of knowledge" (p-value = 0.044), "paracetamol is considered an antibiotic" (p-value < 0.001) and "overuse of antibiotics can cause antibiotics resistance" (p-value = 0.003). The overall knowledge and attitude of pre-professional students were good in both phases, but their attitude did not improve at a significant level in phase-II. There is a need to put more focus on antimicrobial therapy in their training.
