Scientists and clinicians from Swansea and Milan have found that some people who use the internet a lot experience significant physiological changes such as increased heart rate and blood pressure when they finish using the internet. The study involved 144 participants, aged 18 to 33 years, having their heart rate and blood pressure measured before and after a brief internet session.

By adding an experimental drug to a standard chemotherapy regimen, a subset of patients with metastatic pancreatic cancer had a significantly longer period before the cancer progressed as compared with those who received the standard treatment, according to a Phase 2 clinical trial led by an investigator at Fred Hutchinson Cancer Research Center.

New research challenges established medical practice that all heart attack patients should be on beta blockers. The study - by a research team at the University of Leeds - looked at patients who had a heart attack but did not suffer heart failure - a complication of a heart attack where the heart muscle is damaged and ceases to function properly. It found that heart attack patients who did not have heart failure did not live any longer after being given beta blockers - yet around 95% of patients who fall into this category end up on the medication.

Researchers at Karolinska Institutet in Sweden have managed to synthesise lung surfactant, a drug used in the care of preterm babies, by mimicking the production of spider silk. Animal studies reveal it to be just as effective as the biological drugs currently in clinical use. The study is published in Nature Communications.

A genetic variant that protects the heart against cardiovascular disease has been discovered by researchers at the Wellcome Trust Sanger Institute and their collaborators. Reported today in Nature Communications, the cardioprotective variant was found in an isolated Greek population, who are known to live long and healthy lives despite having a diet rich in animal fat.

One in three people who suffer from high blood pressure are failing to take medication as prescribed by their healthcare professionals, a new study led by the University of Leicester has suggested. A study on 1,400 hypertensive patients, conducted in collaboration between the Universities of Leicester (lead authors Dr Pankaj Gupta, Dr Prashanth Patel from the Department of Cardiovascular Sciences at the University of Leicester), Manchester (Prof M Tomazweski) and Czech Republic (Prof J Widimsky) has used a novel urine test to find that non-adherence to prescribed medications is around 30-40%.

A Loyola University Chicago study has found that abnormal proteins found in Alzheimer's disease, Parkinson's disease, and Huntington's disease all share a similar ability to cause damage when they invade brain cells. The finding potentially could explain the mechanism by which Alzheimer's, Parkinson's, Huntington's, and other neurodegenerative diseases spread within the brain and disrupt normal brain functions.
