Background: Food insecurity is associated with poor health and development among young children, with inconsistent findings related to longitudinal growth.
Objective: To investigate associations between household and child food insecurity and young children's weight trajectory during ages 0-2 years.
Design: Longitudinal survey data were analyzed for years 2009-2018.
AbstractInvasions of freshwater habitats by marine fishes provide exceptional cases of habitat-driven biological diversification. Freshwater habitats make up less than 1% of aquatic habitats but contain ∼50% of fish species. However, while the dominant group of freshwater fishes (Otophysi) is older than that of most marine fishes (Percomorphaceae), it is less morphologically diverse.

- Chronic rhinitis in children is linked to significant health issues and varies widely in symptoms, highlighting the need to define specific phenotypes for better treatment.
- The study tracked 485 urban children from ages 1 to 11 to identify patterns of rhinitis and their connections to early life factors, other allergies, and nasal cell gene expression.
- Four rhinitis phenotypes were found: low/minimal, persistent, persistent decreasing, and late increasing, with persistent symptoms associated with increased allergic sensitization and specific risk factors like frequent colds and antibiotic use.

Article Synopsis
- Pathogens like bacteria, fungi, and viruses live in soil and water and can cause infections in humans and animals, especially from decaying matter.
- About one-third of diseases in humans are caused by these pathogens, which can survive outside living things for a long time.
- Researchers are studying how a specific pathogen called Mycobacterium ulcerans spreads in water and found that it's really important to understand how these germs live and grow to better prevent diseases caused by them.
Article Synopsis
- - Predicting outbreaks of infectious diseases requires interdisciplinary research that focuses on how diseases are transmitted and experienced, emphasizing the role of diverse species beyond just vertebrates.
- - Current understanding of mycobacterial diseases is mainly based on studies of infections in vertebrates, but new literature suggests a need to consider interactions with non-vertebrate organisms that could shape disease transmission and risk.
- - The findings challenge prevailing theories of human transmission and advocate for an ecological and evolutionary approach, offering new perspectives on disease prevention and management strategies.
