Educational interventions at Early Head Start led to decline in pediatric emergency visits

Researchers found that integrating URI education into Early Head Start programs led to a decline in pediatric emergency visits and adverse care practices among predominantly Latino families. The intervention showed promise in addressing health literacy gaps, with significant reductions in over-the-counter medication misuse.

Doctor's specialty predicts feeding tube use

A new study by Brown University researchers found that hospital attending physicians' specialties are linked to the likelihood of patients receiving gastric feeding tubes, which is not recommended for frail, terminal patients. The study analyzed tens of thousands of cases over a decade and found that patients cared for by primary care ...

Scientists uncover startlingly new functional details of common anti-diabetic drugs

Scientists at Scripps Research Institute have discovered a new binding site on peroxisome proliferator-activated receptor-gamma (PPARG) that could lead to improved insulin-sensitizing drugs. This alternative site may provide clues to the adverse effects of existing anti-diabetic medications, such as bone loss and congestive heart failure.

New light shed on key bacterial immune system

Bacteria have been found to possess a surprisingly flexible immune system that can recognize and neutralize viruses and other foreign DNA invaders. This adaptive immunity, termed CRISPR-Cas, allows bacteria to store genetic memories of past infections and respond quickly to future exposures.

Longer catch-and-release time leaves largemouth bass nests more vulnerable to predators

A study found that catch-and-release angling creates a window of opportunity for brood predators to consume young largemouth bass. After being caught and released, the male takes an average of 30 minutes to return to its nest, allowing predators to quickly exploit the vulnerability.

Health benefits of 'green exercise' for kids shown in new study

Children who engage in 'green exercise' while cycling experience lower post-activity blood pressure compared to those without visual stimulus. The study suggests that nature scenes promote positive health effects, potentially encouraging public health practitioners to prescribe outdoor exercise.

Friedreich's ataxia -- an effective gene therapy in an animal model

A gene therapy approach using adeno-associated virus (AAV) successfully treated heart disease in mice with Friedreich's ataxia, restoring full functionality to the hearts. The treatment, which introduced a normal copy of the FXN gene, prevented the development of heart disease and even fully cured advanced-stage cases.

Smoking visibility mapped for the first time

Researchers from the University of Otago used mapping methods to track smoking visibility in public areas of downtown Wellington. They found that up to 116 smokers could be seen outside bars and cafés, highlighting the need for smokefree policies to reduce the normalisation of smoking.
