Abstract

In dengue-endemic countries such as Indonesia, Zika may be misdiagnosed as dengue, leading to underestimates of Zika disease and less foreknowledge of pregnancy-related complications such as microcephaly. Objective: To assess the attitudes of frontline physicians in a dengue-endemic country toward testing for Zika infection among patients with dengue-like illnesses. Methods: A cross-sectional online survey was conducted among general practitioners (GPs) in Indonesia. The survey assessed their attitude and also collected sociodemographic data, characteristics of their medical education, professional background, and workplace, and exposure to Zika cases. A two-step logistic regression analysis was used to assess possible variables associated with these attitudes. Results: A total of 370 GPs were included in the final analysis of which 70.8% had good attitude. Unadjusted analyses suggested that GPs who were 30 years old or older and those who had medical experience five years or longer had lower odds of having a positive attitude compared to those who aged younger than 30 years and those who had medical experience less than five years, OR: 0.58; 95%CI: 0.37, 0.91 and OR: 0.55; 95%CI: 0.35, 0.86, respectively. No explanatory variable was associated with attitude in the fully adjusted model. Conclusion: Our findings point to younger GPs with a shorter medical experience being more likely to consider testing for Zika infection among their patients presenting with dengue-like illnesses. Strategic initiatives may be needed to enhance older or longer-experienced physicians' capacity in diagnosing Zika infection.

Abstract

This study tackles the pressing challenge of lung cancer detection, the foremost cause of cancer-related mortality worldwide, hindered by late detection and diagnostic limitations. Aiming to improve early detection rates and diagnostic reliability, we propose an approach integrating Deep Convolutional Neural Networks (DCNN) with Explainable Artificial Intelligence (XAI) techniques, specifically focusing on the Residual Network (ResNet) architecture and Gradient-weighted Class Activation Mapping (Grad-CAM). Utilizing a dataset of 1,000 CT scans, categorized into normal, non-cancerous, and three types of lung cancer images, we adapted the ResNet50 model through transfer learning and fine-tuning for enhanced specificity in lung cancer subtype detection. Our methodology demonstrated the modified ResNet50 model's effectiveness, significantly outperforming the original architecture in accuracy (91.11%), precision (91.66%), sensitivity (91.11%), specificity (96.63%), and F1-score (91.10%). The inclusion of Grad-CAM provided insightful visual explanations for the model's predictions, fostering transparency and trust in computer-assisted diagnostics. The study highlights the potential of combining DCNN with XAI to advance lung cancer detection, suggesting future research should expand dataset diversity and explore multimodal data integration for broader applicability and improved diagnostic capabilities.

Abstract

Yellow fever still represents a major public health threat in Africa largely due to inadequate vaccine supply, insufficient vaccine coverage, increase in people without of vaccination living in endemic areas and occupation of individuals. The aim of this study was to assess the acceptability to yellow fever vaccination among skilled and unskilled workers in selected African countries. This cross sectional online survey was carried out between 19 January 2022 and 31 December 2022, in five African countries (Cameroon, Egypt, Nigeria, Sudan and the Gambia). The responses to the survey were collected by Survey Monkey and the links were distributed via Facebook, Twitter, and WhatsApp. Data were collected using self-administered structured questionnaire, and analysed. A total of 1340 respondents (601 skilled workers, 739 unskilled workers) participated in the survey of which 616 of them indicated had yellow fever vaccination. Proportion of the unskilled workers with history of vaccination was less than those of the skilled workers (35.5% vs 58.9%). Location (OR=31.04, p=0.000), age (OR=146.95, p=0.001), religion (OR=24.42, p=0.012), education (OR=116.41, p=0.001), marital status (OR=68.83, p=0.001) and monthly household income (OR=87.62, p=0.001) were significantly associated with acceptance to receive YF vaccine. In addition, more of the skilled workers were very willing to receive the YF vaccine compared to their unskilled counterparts (p0.001). This study suggests that unskilled workers are less likely to be vaccinated against yellow fever than skilled workers, hence the need for strategic public health interventions to reach this category of people in the society.
