    Get PDF
    Early detection of breast cancer through mammography is vital, with calcifications in mammograms serving as key indicators. Distinguishing between benign and malignant calcifications is essential for accurate diagnosis and treatment. This study aims to develop a Computer-Aided Detection (CAD) system to identify and classify breast calcifications. Data from confirmed breast cancer cases were collected from the Laboratory Information System (LIS) at the Women Imaging Suite (WISH) of Hospital Universiti Sains Malaysia (HUSM) and cross-verified with the Picture Archiving and Communication System (PACS) to select mammograms showing calcifications that met the inclusion criteria from September 2020 to December 2023. The performance of Support Vector Machine (SVM), K-Nearest Neighbors (KNN), and Random Forest (RF) models was evaluated using metrics such as accuracy, F1 score, recall, precision, specificity, sensitivity, and area under the curve (AUC). The SVM model showed balanced performance with 65.22% accuracy and an F1 score of 0.6, indicating a trade-off between precision (54.55%) and recall (66.67%). The KNN model had the lowest performance with 47.83% accuracy and an F1 score of 0.4, highlighting classification challenges. The RF model performed moderately with 60.87% accuracy and an F1 score of 0.47, showing high specificity (71.43%) but lower sensitivity (44.44%). Achieving 95% accuracy remains difficult due to reliance on high pixel value detection, limited complexity of machine learning models, and data constraints. Enhancing feature extraction, data augmentation, and model optimization could improve accuracy. Combining machine learning with deep learning or using ensemble methods offers promise for better classification, ultimately improving patient management

    A comprehensive 3D dosimetric analysis of the vienna ring applicator in high-dose-rate (HDR) brachytherapy for cervical cancer treatment: TLD measurement

    Get PDF
    Introduction: Intracavitary brachytherapy is the most common approach used for gynecological cancers which happens to be the cancer with highest occurrence among women. Intracavitary-interstitial (IC/IS) brachytherapy is an approach that is developed, and various applicators are utilised in this treatment method such as the Vienna Ring applicator. However, a comprehensive understanding on the dosimetric behavior of Vienna Ring applicator is required for efficient use in brachytherapy for cervical cancer. Purpose: This study aims to experimentally analyse the dosimetric performance of Vienna Ring applicator in aspects of target coverage, organ at risk (OAR) sparing and ability to deliver the planned dose during treatment. Methods and Materials: A Vienna Ring applicator was assembled in a pelvic phantom with Thermoluminescence Dosimeters (TLD-100) chips were attached to the OARs (bladder and rectum) to act as markers. Computed Tomography (CT) images were obtained for treatment planning. 7Gy was prescribed for irradiation and the treatment was planned for the assessment of dose received by target, OAR and the TLDs at 8 points. The dose measured by the TLD-100 chips during the irradiation and dose calculated by treatment planning system (TPS) on the TLD points were compared. Results: The dose received by target, bladder and rectum are 7.1 Gy, 2.4 Gy and 7.4 Gy respectively as obtained from TPS. Out of 8 TLDs, 7 TLDs have dose deviation less than 20% while 1 TLD (F7) have dose deviation of 31.03% between measured and calculated dose. Conclusion: The dose distribution of Vienna ring applicator to GTV is not homogenous but has high degree of conformity. The Vienna ring applicator was able to spare the bladder and deliver optimum dose to tumour. The Vienna ring applicator can deliver planned dose during treatment delivery due to 90% of the dose deviation was below 20%. Therefore, the applicator can be categorised as a reliable applicator in brachytherapy for cervical cancer

    Asthma food taboos are a set of food prohibitions that may cause asthma attacks. These will impact how well asthma is treated medically. The objectives of this study aim to determine the knowledge, attitude and practice of asthma food taboos and its associated factors among parents of asthmatic children in Hospital Universiti Sains Malaysia. A cross-sectional study design was conducted in this study. Data was collected using a Google Forms. A total of 344 parents with asthmatic children in Hospital USM who fulfilled the inclusion and exclusion criteria were approached to participate in this study. Data collected were statistically analysed using the SPSS software version 27.0. This study showed that 59.9% of respondents have poor knowledge, 67.4% have a positive attitude and 61.3% practice asthma food taboos. There was no correlation between knowledge with attitude (p= 0.663) and knowledge with practice (p=0.683) meanwhile there was a correlation between attitude and practice (p=0.001). Lastly, there was an association between sociodemographic factors [age (p=0.000), and religion (p=0.015)] with the practice of asthma food taboos. Meanwhile, there was no association between sociodemographic factors [ethnicity (p=0.069), and educational level (p=0.831)] with the practice of asthma food taboos among parents with asthmatic children in Hospital USM. It is concluded that parents with asthmatic children have poor knowledge, positive attitudes and high practice of asthma food taboos. Health practitioners must learn more about how culture influences diets and foods that could be harmful or fatal for people with asthma and promote changes in knowledge, attitude, and practice of these asthma food taboos

    Most of the outpatient community has access to analgesic medication, especially over-the-counter analgesic medication. Both prescribed and non-prescribed analgesic medication should be consumed correctly to prevent it from being abuse. Therefore, this study aims to determine knowledge and attitude of analgesic use among outpatients in Hospital Universiti Sains Malaysia (HUSM). A total of 220 participants from outpatient community at HUSM were involved in this study by answering self-administered questionnaire through physical form of questionnaire send to them. This study is one of cross-sectional study. The collected data was analyzed through SPSS version 27.0. The level of knowledge and the level of attitude of analgesic use were identified using descriptive statistics. Meanwhile, the association between selected sociodemographic characteristic (age, gender, level of education) with level of knowledge of analgesic use, and association between sociodemographic characteristic (age, gander, level of education) with level of attitude of analgesic use were analyzed using Pearson Chi-Square. Unexpectedly, most of the outpatient community at HUSM have a fair level of knowledge and fair level of attitude of analgesic use with 52.3% and 46.4% respectively. However, the factor that influences lack of knowledge and attitude among outpatient community was not identified in this study as it shows no association between selected sociodemographic characteristics (age, gender, level of education) with neither level of knowledge of analgesic use, nor level of attitude of analgesic use. Regardless of the finding, an appropriate actions and strategies should be taken immediately to solve these issues and improve the knowledge and the attitude of analgesic use among outpatient community setting so that the community have better understanding and having good attitude of analgesic use and consume it in correct ways

    In China’s interpreter training programs, efforts to systematically develop and enact a formative assessment regime has been rarely documented in the extant body of scholarship. To gain a more comprehensive understanding of the applicability and impact of formative assessment regime, the present study adopted a multi-phase approach to explore the development, implementation, and learned lessons of a formative assessment regime in an interpreter training program at Xinyang Agriculture and Forestry University, a focal and representative institution of higher education in China. The researcher recruited 129 second-year interpreter learners, 7 lecturers, and 10 experts as participants in the study. Methodologically, an embedded experimental design was adhered to in the study to comprehensively include the pre-intervention, intervention, and post-intervention phases within a unified research framework. For the pre-, and post-intervention phases, the research used in-depth interview and focus group discussions to obtain viewpoints and understandings of trainees and trainers, and Delphi method for evaluative judgement of the experts. For the intervention phase, mixed-method quasi experimental approach was chosen to examine the effects of the developed formative assessment regime on the academic achievement, motivation, and collaboration in interpreter training, which were measured through a summative interpreting achievement test (SIAT), an interpreter learning motivation questionnaire (ILMQ), and naturalistic observation of classroom conversations respectively
