Discovery of a clandestine ticking bomb - blunt traumatic aortic injury

Blunt traumatic aortic injury (BTAI) is a crucial diagnosis to be made early in the management of trauma patients with aims to improve survival outcome. The objective of this case report is to highlight and explore the role of imaging especially Computed Tomography Angiography (CTA) thorax to diagnose a focal traumatic aortic isthmus pseudoaneurysm in a young gentleman sustaining high impact thoracic trauma

COVID-19 Vaccine Acceptance and Its Determinants among Medical Students at the Universiti Malaysia Sabah: A Cross-Sectional Study

Malaysia has announced the COVID-19 National Immunization Programme (NIP) involving three phases beginning in March 2021, with the target of vaccinating 80 percent of the population. The purpose of this study was to determine whether medical students at the Faculty of Medicine and Health Sciences (FMHS), Universiti Malaysia Sabah (UMS), were accepting of the COVID-19 immunization and the factors that may have contributed to that acceptance. Methods: A cross-sectional online study involving 244 medical students from FMHS, UMS, was carried out utilizing a validated electronic questionnaire. The questionnaire was divided into three sections: variables influencing COVID-19 vaccine acceptability, sociodemographic characteristics of the students, and their acceptance of the vaccine. The IBM Statistical Package for Social Sciences (SPSS) was used to statistically analyze the data. Results: 91.4% of people accepted the COVID-19 vaccine, which is among the highest rates among studies done in academic settings. Vaccine information from health agencies was found to be significantly associated with the acceptability of the COVID-19 vaccination (p=0.02) and confirmed by multivariable analysis as its determinant (prevalence odds ratio 9.535, 95% confidence interval 3.931-15.138, p-value: 0.004). Conclusion: This study merits the attention of the public health department of FMHS, UMS to plan cooperative synergy with regional health organizations like the Malaysian Health Coalition (MHC) to improve knowledge and raise awareness about the COVID-19 vaccination while also giving medical students evidence-based information

Comparison of water saturation models based on well logging data : a case study of MX field in Malay Basin

One of the primary methods to determine water saturation is logging measurement which uses water saturation models. Archie`s interpretation model to estimate water saturation in clean formations has successfully been useful over the years. However, in shaly sand formation this model yields inaccurate water saturation estimates due to shaly sand effects. Many shaly sand interpretation models have been developed; unfortunately; there is no unique water saturation model which works best for all formations as subsurface information may be limited and formation shaly sands may vary. Nevertheless, some water saturation models provide more accurate water saturation values for a formation. Thus, this study aimed to determine the water saturation alternative by using Dual-Water, Waxman-Smits, Indonesian, and Modified Simandoux models. The results showed that the Indonesian Model and Modified Simandoux gave the closest water saturation values with more than 80% similarities compared with logging analysis and thus should be considered the best models. Therefore, it is hoped that the findings can help improve knowledge on the selection of water saturation models best suited to the nature of formation similar to the wells, especially to other hydrocarbon exploration in the Malay Basin
