Abstract

Cervical cancer is one of the most prevalent cancer in the world and caused by Human Papilloma Virus (HPV). The pathogenesis of cancer as whole (50%) is caused by gene mutation. HPV stimulates carcinogenesis on cervix epitel cells by HPV-Encoded viral oncoproteins, E6 and E7, which will inhibit tumor suppressor gene activation, such as p53 gene. HPV-encoded E6 oncoprotein  is able to directly attached on p53 causing degeneration via E6-AP-mediated ubiquitination pathway. Moreover, overexpression on YY1 gene has significant role on the progression of HPV on cervical cancer. YY1 inhibits p53 activation dan inhibits apoptosis on cells infected by HPV. Overexpression of YY1 induces reduction of endogenous p53, which will inhibit p53 function as tumor suppressor gene.Keywords: cervical cancer, HPV, P53, YY1

Abstract

Background: Coronavirus Disease 2019 drastically modulate the healthcare world. The pandemic's immense transmission and lethality rate enforce the Indonesian Medical Doctor Proficiency & Competency Test to discard practical measures and rely only on a written exam. These with pandemic social and physical restrictions impede prospective doctors’ learning opportunities leading to easier failure. Henceforth, the present study has high urgency to identify and manage failure factors, especially during the pandemic. Methods: The cross-sectional study examines 75 clinical medical students through purposive analysis with an online questionnaire in August 2021. Data are analyzed with Chi-Square, Mann-Whitney, and binary logistics. Result: Respondents have an average age of 24.15 (1.322) years old, majorly female (82.7%), and pass as first takers (86.7%) with 1.27 (0.949) off-campus tutelage. The significant factors for the test failure are depression and economic status. The study developed a failure prediction model with the area under the curve 0.845, cut-off 366.5, 80.0% sensitivity, and 84.6% specificity. Conclusion: Intrinsic, extrinsic, and academic factors have significant roles in the failure outcome. For this reason, preparation is crucial not only among individuals but also in institutions. The study also provides feedback about the importance of mental health and economic status for Indonesian medical students.
