Purpose: Low-field (LF) MRI scanners are common in many Low- and middle-Income countries, but they provide images with worse spatial resolution and contrast than high-field (HF) scanners. Image Quality Transfer (IQT) is a machine learning framework to enhance images based on high-quality references that has recently adapted to LF MRI. In this study we aim to assess if it can improve lesion visualisation compared to LF MRI scans in children with epilepsy.

- Low-field MRI scanners (<1T) are often used in low- and middle-income countries and for specific patient groups in wealthier nations, but they typically produce lower resolution and contrast images compared to high-field MRI scanners (1.5T and above).
- The study presents a technique called Image Quality Transfer (IQT) that enhances low-field MRI images by estimating high-field quality images based on the available low-field images using advanced modeling and machine learning approaches.
- Results indicate that the IQT method improves the contrast and resolution of low-field MR images, making them more useful for detecting anatomical structures and issues, thereby increasing their diagnostic potential in resource-constrained environments.
Background: Developmental assessment remains an integral part of the routine evaluation of the wellbeing of every child. Children in resource-poor countries are not routinely assessed for signs of developmental delay and developmental disorders are frequently overlooked. A major gap exists in the availability of culturally appropriate and cost-effective developmental screening tools in many low and middle income countries (LMICs) with large populations.

This study aimed to evaluate the spectrum of adverse events following immunization with the COVID-19 AstraZeneca/Oxford vaccine in Ibadan, southwestern Nigeria.
Methodology: A cross-sectional study.
The Kidney Disease: Improving Global Outcomes (KDIGO) advocates the use of dipstick proteinuria as a primary screening tool. However, the performance of dipstick urinary for proteinuria has been adjudged to be weak, unreliable with poor predictive value. This study aimed to determine and compare significant proteinuria (SP) using spot urinary protein-to-creatinine ratio (UPr/UCr) as a primary screening tools with dipstick proteinuria among the high-risk African children.
