Thousands 'miss out on stroke treatment'
About 9,000 stroke patients a year are missing out on a treatment that can prevent disability following a stroke, say UK experts. Clot retrieval can restore blood flow to the brain, preventing some lasting damage, but currently only 600 patients a year get this therapy, they estimate. A national stroke audit reveals part of the problem is a lack of skilled staff to do the procedure. NHS England says stroke patients are receiving high quality care. During a stroke, the blood supplyi...
Lung cancer cells spread like unanchored tents, study says
Spreading lung cancer cells are like tents which have collapsed and are adrift in the wind, scientists from the University of York have discovered. Communication between two proteins is what triggers the cell tent to lose its shape and become unanchored, their research found. This allows the cells to travel to other areas of the body. The researchers said their findings could help prevent the spread of lung cancer. Writing in the Journal of Clinical Investigation, researchers from York and t...
Predatory bacteria can wipe out superbugs, says study
Predatory bacteria - that eat others of their kind - could be a new weapon in the fight against superbugs, say UK researchers. Experiments showed a dose of Bdellovibrio bacteriovorus acted like a "living antibiotic" to help clear an otherwise lethal infection. The animal studies, published in Current Biology, suggested there would be no side effects. Experts said the approach was unusual, but should not be overlooked. Fear of an antibiotic apocalypse, caused by growing le...
Terminally ill teen won historic ruling to preserve body
A 14-year-old girl who wanted her body to be preserved, in case she could be cured in the future, won a historic legal fight shortly before her death. The girl, who was terminally ill with a rare cancer, was supported by her mother in her wish to be cryogenically preserved - but not by her father. She wrote to the judge explaining that she wanted "to live longer" and did not want "to be buried underground". The girl, who died in October, has been taken to the US and preserved there. A High C...
Dementia game 'shows lifelong navigational decline'
The world's largest dementia research experiment, which takes the form of a video game, has indicated the ability to navigate declines throughout life. The findings, presented at the Neuroscience 2016 conference, harnessed data from 2.4 million people who downloaded the game. Getting lost is one of the first symptoms of Alzheimer's disease. And the researchers at University College London believe the results could help make a dementia test. Sea Hero Quest is a nautical adventure to save...
'First flu' affects lifetime risk
A person's chances of falling ill from a new strain of flu are at least partly determined by the first strain they ever encountered, a study suggests. Research in Science journal looked at the 18 strains of influenza A and the hemagglutinin protein on its surface. They say there are only two types of this protein and people are protected from the one their body meets first, but at risk from the other one. A UK expert said that could explain different patterns in flu pandemics. The researcher...
'Brain wi-fi' reverses leg paralysis in primate first
An implant that beams instructions out of the brain has been used to restore movement in paralysed primates for the first time, say scientists. Rhesus monkeys were paralysed in one leg due to a damaged spinal cord. The team at the Swiss Federal Institute of Technology bypassed the injury by sending the instructions straight from the brain to the nerves controlling leg movement. Experts said the technology could be ready for human trials within a decade. Spinal-cord injuries block the flow of...
Zika therapy 'works in the womb'
Scientists say they may have found a way to protect babies in the womb from the harmful effects of Zika. So far the US team has only had success in mice with its antibody treatment, but it says it might eventually lead to a therapy for women who catch Zika in pregnancy. The Zika virus can severely damage a newborn's brain. The antibody therapy is made using blood cells from people who have recently had and fought off Zika. In mice, the treatment significantly reduced the amount of Zika virus...
Warning over non-lump breast cancers
Around one in six cases of breast cancer begins with symptoms other than a suspect lump, experts are warning. Researchers from University College London say women need to be aware of other warning signs - such as nipple changes - so that they get help fast. The researchers examined the symptoms of 2,300 women who had recently been diagnosed with breast cancer. They found that women with non-lump symptoms were more likely to put off visiting their doctor. The researchers are presenting their ...
Gut bacteria 'may help drugs fight cancer'
Bacteria living deep inside the digestive system seem to alter how cancer drugs work, a study suggests. Immunotherapies - which harness the body's own defences to fight tumours - can clear even terminal cancer in a small proportion of patients. However, a small study by the University of Texas found those harbouring a more diverse community of gut bugs are more likely to benefit. Cancer Research UK said understanding gut bugs had "great potential". The human body is home to trillions of micr...
Smoking 'causes hundreds of DNA changes'
Smoking leaves an "archaeological record" of the hundreds of DNA mutations it causes, scientists have discovered. Having sequenced thousands of tumour genomes, they found a 20-a-day smoker would rack up an average of 150 mutations in every lung cell each year. The changes are permanent, and persist even if someone gives up smoking. Researchers say analysing tumour DNA may help explain the underlying causes of other cancers. Pamela Pugh, 69, was diagnosed with lung cancer in 2013. She started...
UK forms global infection response team
The UK has created a specialist team of health experts who can be deployed anywhere around the world within 48 hours if a disease outbreak strikes. The aim is to stamp out infections like Ebola before they spread far and wide. The scientists, academics and clinicians will be funded by £20m from the government over five years. When not responding to an immediate emergency, the rapid response team will assess future disease threats and train colleagues from home and abroad. Public Health...
Landmark chronic fatigue trial could treat two-thirds
A therapy that successfully treats two-thirds of children with chronic fatigue syndrome is being trialled for NHS use. The disease affects one in 50 children, leading to mental health problems and missing school. "If anyone has done a cross-country [run] or a marathon - that is how it feels all the time," said Jessica, 14. The trial, on 734 children, will use intensive online therapy sessions to adjust sleeping habits and activity levels. It also uses a form of behavioural therapy to help ch...
The venom of one of world's deadliest snakes could relieve pain, say scientists
A snake with the largest venom glands in the world could hold the answer to pain relief, scientists have found. Dubbed the "killer of killers", the long-glanded blue coral snake is known to prey on the likes of king cobras. The venom of the two-metre-long snake native to South East Asia acts "almost immediately" and causes prey to spasm. New research published in the journal Toxin found it targets receptors which are critical to pain in humans and could be used as a method of treatm...
