Young-onset diabetes (YOD) is characterised by unique diagnostic and management challenges more pronounced in resource-limited settings like Sri Lanka. We aimed to ascertain the prevalence, patterns and characteristics of YOD in Sri Lanka and describe the state of care. Retrospective review of baseline data of all patients enrolled in the prospective multicentre Database for Young-Onset Diabetes, Sri Lanka (DYOD-SL), was performed, from April 2021 to April 2023.

Article Synopsis
  • - Clinical fetal monitoring is typically expensive, requires medical professionals, and has issues like false positives and radiation exposure, leading to a demand for more accessible and cost-effective alternatives in obstetrics.
  • - This study introduces a wearable device for home use that monitors fetal movements and distress comfortably and non-invasively during the final trimester, using a microcontroller, accelerometer, and a low-cost microphone.
  • - The prototype features a GSM-based alert system for immediate notifications and has demonstrated zero false negatives in detecting fetal movements, validating its effectiveness against an open-source database.

Circular leaf spot (CLS) disease poses a significant threat to persimmon cultivation, leading to substantial harvest reductions. Existing visual and destructive inspection methods suffer from subjectivity, limited accuracy, and considerable time consumption. This study presents an automated pre-identification method of the disease through a deep learning (DL) based pipeline integrated with optical coherence tomography (OCT), thereby addressing the highlighted issues with the existing methods.

Speckle patterns are a generic feature in coherent imaging techniques like optical coherence tomography (OCT). Although speckles are granular like noise texture, which degrades the image, they carry information that can be benefited by processing and thereby furnishing crucial information of sample structures, which can serve to provide significant important structural details of samples in longitudinal pre-clinical monitoring and assessments. Since the motions of tissue molecules are indicated through speckle patterns, speckle variance OCT (SV-OCT) can be well-utilized for quantitative assessments of speckle variance (SV) in biological tissues.
