Nour Ghalia Abassi
Speaker at AMLD Africa 2024, AMLD Africa 2022 and AMLD Africa 2021
Nour Ghalia Abassi is a Business Leader at DigeHealth and a Data Scientist with a specialized interest in sound recognition in gastro-enterology.
With an educational background focused on integrating AI into medtech.
With her team at DigeHealth, Nour has developed a medtech device designed to monitor patients with bowel disorders by recognizing, counting and categorizing bowel sounds. This innovation reflects Nour Ghalia’s commitment to applying data science to improve patient outcomes.
Her work in data science is directed towards creating a system capable of flagging anomalies. It aims to distinguish non-invasively between normal and abnormal bowel behaviors, underscoring her commitment to advancing non-intrusive diagnostic methods in healthcare.

Impact of bowel sounds on symptoms and colonoscopy outcomes
We utilized a modified stethoscope to capture digital recordings, amassing over 500 minutes of real patient data. Alongside these recordings, we diligently documented pertinent metadata from each patient, including specific symptoms, their Bristol scale ratings, and relevant medical antecedents. We employed machine learning algorithms with dual objectives: firstly, leveraging deep learning, we used a sequence of two Convolutional Neural Networks to craft a bowel sound recognition model that boasts an accuracy of 80%; and secondly, utilizing statistical models to evaluate the feature importances in predicting bowel sounds and symptoms. By engineering sound features, we were able to predict individual symptoms. Notably, our findings revealed that certain sound features possess p-values less than 1% when correlated with bowel symptoms. The overarching aim of this research is to unearth potential correlations between bowel sounds, manifested symptoms, and outcomes from colonoscopy examinations. Advancing research on the relationship between bowel sounds and bowel disorders holds the potential to revolutionize gastroenterology.
