Kawasaki disease and pregnant women

Researchers at UC San Diego have found that the health risks to pregnant women with a history of Kawasaki disease (KD) are low with proper management and care. The study, published in British Journal of Obstetrics and Gynaecology, also notes that the long-term risk for adults with KD is not known.

Misplaced protein causes heart failure

A new study published in Circulation reveals how changes in the organized cell membrane network of heart muscle leads to heart failure. Colchicine, a drug used for gout treatment, protects normal heart function by reducing microtubule density, while taxol accelerates damage during heart failure.

Eating red and processed meat -- what do scientists say?

A recent perspective paper cautions about uncertainties in scientific evidence linking red and processed meat to increased cancer risk. The review discusses differences between animal studies and human data, suggesting that other foods may protect the gut from potential adverse effects of meat.

Early detection helps manage a chronic graft-vs.-host disease complication

Researchers found that a simple questionnaire predicting lung involvement improves patient outcomes in chronic graft-vs.-host disease. A score of 3 indicates shortness of breath at rest or requiring oxygen, associated with higher mortality. Early detection enables timely treatment to reduce symptoms and improve survival.

Human activity influences beach bacterial diversity

Bacterial community composition at two beaches shows distinct differences but also similarities, suggesting regional human impact variations. Higher bacterial diversity at one site indicates better ecological health and resiliency to sewage contamination.

3-D scans map widespread fish disease

Researchers at the University of Copenhagen have used 3D scans to map the widespread fish disease enteric redmouth disease. The study reveals that the bacteria infects fish through their ultra-thin gills, providing a new understanding of the infection pathway and potential solutions.

New molecules doom proteins with kiss of death

Researchers at Cornell University have developed a new type of antibody, called a ubiquibody, which can target specific proteins for destruction. This technology could provide a powerful way to fine-tune research on protein deletion or reduction, and may also prove useful for future drug therapies.

B-cells aggravate autoimmune diseases

Scientists have discovered that B-lymphocytes lack the protein PTP1B, making them hyperactive and promoting an autoimmune attack. This study provides a new mechanism for how B-cells regulate an immune response, potentially playing a significant role in autoimmune diseases such as rheumatoid arthritis.

Heart failure unknowns a roadblock to managing health

A systematic review of 49 studies found that patients with heart failure and their families often lack basic knowledge about the condition, leading to confusion, delays in seeking help, and uncertainty about long-term care. This lack of understanding can decimate quality of life and is a major reason seniors end up in emergency rooms.

Smart grid for electric vehicle fleet

The Fraunhofer Institute's micro smart grid demonstrator is designed to manage EV fleets efficiently, avoiding short circuits during peak load times. The system aims to provide electricity exclusively from renewable sources, reducing the country's reliance on imported electricity and mitigating power outages.
