Combination therapy stops loss of kidney function in rare genetic disease

Researchers have discovered that combining two blood pressure-lowering drugs with enzyme replacement therapy can slow the progression of kidney disease in patients with severe Fabry disease. The study found significant reductions in proteinuria and minimal decline in kidney function after an average of two and a half years' treatment.

Humboldt squid on the move

Large Humboldt squid have invaded the sea off Central California, where they are feeding on commercially important fishery species like hake and anchovy. This shift may be linked to a decrease in large tuna and billfish populations in the Equatorial Pacific, allowing the squid to expand their range.

White blood cell booster may help cancer patients avoid deadly complications

A study led by Duke University researchers found that a white blood cell booster can significantly reduce the risk of chemotherapy-related complications characterized by fever and low white blood cell levels. The study, published in the Journal of Clinical Oncology, involved over 3,000 patients and showed that patients taking the drug ...

Obesity is 'socially contagious'

A study by Harvard and the University of California, San Diego found that obesity is socially contagious, spreading from person to person in a social network. The greatest effect was seen among friends, with a 171% increase in chances of becoming obese if a mutual friend becomes obese.

Obesity spreads through social networks

Researchers found that when an individual gains weight, their friends and siblings have a significantly increased risk of becoming obese. The closer two people are in a social network, the stronger the effect. Geographical distance appears to have no effect, suggesting that environmental factors play a smaller role.

Enzyme discovery sheds light on vitamin D

Researchers at Queen's University have made a groundbreaking discovery about the breakdown of vitamin D, revealing that changing a single amino acid in the hydroxylase enzyme can alter its pathway. This finding has significant implications for the treatment of cancer and other diseases associated with vitamin D deficiency.

New model for autism suggests women carry the disorder and explains age as a risk factor

Researchers at Cold Spring Harbor Laboratory propose a new model for understanding how autism is acquired, suggesting that spontaneous germ-line mutation is a significant cause. This mutation can be carried by women without severe symptoms and passed on to their children, increasing the risk of sons developing autism.

Older is better -- Top-10 comparison of diabetes drugs give metformin top grade

A study by Johns Hopkins Medicine found that metformin, a widely used diabetes medication, offers distinct advantages over nine other medications in controlling blood sugar levels, weight gain, and bad cholesterol levels. The medication was also found to be less expensive than newer options, with annual treatment costs averaging $100.

Success rates for prostate cancer depend on experience of surgeon

A study published in the Journal of the National Cancer Institute found that experienced surgeons perform more successful prostate cancer surgeries, with a steeper learning curve. As surgeons gain experience, patient outcomes improve, but beyond 250 operations, additional experience has little influence on cancer recurrence rates.
