A family of peptides known as bioactive peptides has unique physiological properties and may be used to improve human health and prevent illness. Because bioactive peptides impact the immunological, endocrine, neurological, and cardiovascular systems, they have drawn a lot of interest from researchers. According to recent studies, bioactive peptides have a lot to offer in the treatment of inflammation, neuronal regeneration, localized ischemia, and the blood-brain barrier.

Environmental enteric dysfunction (EED) is a subclinical enteropathy challenging to diagnose due to an overlap of tissue features with other inflammatory enteropathies. EED subjects ( = 52) from Pakistan, controls ( = 25), and a validation EED cohort ( = 30) from Zambia were used to develop a machine-learning-based image analysis classification model. We extracted histologic feature representations from the Pakistan EED model and correlated them to transcriptomics and clinical biomarkers.

Crohn's disease (CD) is a chronic inflammatory disease of the gastrointestinal tract. A clear gap in our existing CD diagnostics and current disease management approaches is the lack of highly specific biomarkers that can be used to streamline or personalize disease management. Comprehensive profiling of metabolites holds promise; however, these high-dimensional profiles need to be reduced to have relevance in the context of CD.

Article Synopsis
  • - The study explored how environmental factors affect child health in rural Pakistan, particularly focusing on acute respiratory infections (ARIs), diarrhea, and growth, using geographical information systems (GIS) technology.
  • - Data from 416 children revealed that those living closer to secondary hospitals and Maternal Health Centers (MHCs) experienced lower rates of ARIs and diarrhea compared to those near primary healthcare facilities.
  • - The findings suggest that distance to healthcare facilities significantly impacts disease prevalence, indicating potential gaps in public policy that could improve health outcomes in rural areas.

Article Synopsis
  • Hematoxylin and Eosin (H&E) stained Whole Slide Images (WSIs) can vary in appearance due to differences in staining processes across laboratories, which may cause bias in diagnostic assessments.
  • Traditional stain normalization methods can reduce human bias, but deep learning models often struggle to generalize due to their inability to adapt beyond simple linear transformations.
  • The proposed Self-Attentive Adversarial Stain Normalization (SAASN) method utilizes a generative adversarial framework with a self-attention mechanism to effectively standardize stain appearances while maintaining the integrity of biopsy features, outperforming other normalization techniques.

Objectives: Striking histopathological overlap between distinct but related conditions poses a disease diagnostic challenge. There is a major clinical need to develop computational methods enabling clinicians to translate heterogeneous biomedical images into accurate and quantitative diagnostics. This need is particularly salient with small bowel enteropathies; environmental enteropathy (EE) and celiac disease (CD).

Artificial intelligence (AI), a discipline encompassed by data science, has seen recent rapid growth in its application to healthcare and beyond, and is now an integral part of daily life. Uses of AI in gastroenterology include the automated detection of disease and differentiation of pathology subtypes and disease severity. Although a majority of AI research in gastroenterology focuses on adult applications, there are a number of pediatric pathologies that could benefit from more research.
