Majority of children with allergies needlessly avoid common antibiotics

A new study published in Pediatrics found that eight in 10 children who reported being allergic to non-beta-lactam antibiotics were not truly allergic, highlighting the need for improved and timely access to formal allergy evaluations. This can prevent lifelong avoidance of certain antibiotic classes and help combat antibiotic resistance.

First US study shows strong results for procedure to treat knee pain from OA

A new US study demonstrates the effectiveness of genicular artery embolization (GAE) in treating osteoarthritis knee pain. The minimally invasive procedure blocks blood flow to certain parts of the knee, providing rapid relief from pain and disability. Results show significant improvement in pain scores, with nearly all patients experi...

Novel genetic signature that can predict some kinds of breast cancer is identified

Researchers have identified a genetic signature associated with the degree of pathological angiogenesis in breast cancer tumors. The study combined gene expression profiles from public databases with analysis of retinopathy models to uncover key genes involved in pathological angiogenesis, providing a new tool for breast cancer treatment.

Limiting global warming would relieve populations from wet and dry extremes in China

A study published in Science Bulletin finds that limiting global warming to 1.5°C would reduce precipitation extremes in China, particularly in southeastern regions. The research highlights the social impacts of climate change, with heavy rainfall events intensifying across the country and dry extremes increasing in South China.

Moffitt researchers develop more efficient approach to create mouse models

Researchers at Moffitt Cancer Center have developed a new platform for creating genetically engineered mice to study melanoma, which is significantly faster than the traditional approach. This new method uses chimera mouse models and chimera-derived melanoma cell lines to provide a faster way to study skin cancer.

New metrics needed to evaluate and combat HIV epidemics in the US

A commentary published in the American Journal of Public Health argues that existing metrics are insufficient to track the public health response to HIV in the US. Newer metrics are needed to inform and evaluate efforts aimed at reducing new HIV infections by 75% and 90% over the next five and ten years, respectively.

Consider marine life when implementing offshore renewable power

Researchers warn of potential negative impacts of offshore renewable energy on marine life, including head trauma and hearing loss. The study suggests that consideration should be given to the impact of technologies like wind turbines and wave energy converters on marine animals before implementation.

Good aerobic fitness doesn't protect children against type 2 diabetes, staying active does

Good aerobic fitness is not linked to lower risk of insulin resistance in obese children. Instead, more physical activity and less sedentary time were associated with reduced insulin resistance regardless of body fat percentage. The study suggests that more physical activity plays a key role in preventing type 2 diabetes in childhood.
