£6m statin trial raises hope drug can be used to treat multiple sclerosis
Trial involving almost 1,200 people aims to ‘establish definitively’ whether cholesterol drug can slow disability progressionScientists are hopeful a major drug trial will establish that statins can be used to treat multiple sclerosis.The low-cost drugs are typically prescribed to help lower levels of “bad cholesterol” associated with raised risk of a heart attack or stroke, but they have also shown “incredible promise” for the treatment of MS.Continue reading...

Eating cheese does not raise risk of heart attack or stroke, study finds
Consumption of even full-fat dairy products does not increase risk, international team of experts saysConsuming cheese, milk and yoghurt – even full-fat versions – does not increase the risk of a heart attack or stroke, according to research that challenges the widely held belief that dairy products can damage health.The findings, from an international team of experts, contradict the view that dairy products can be harmful because of their high saturated fat content. The experts dismiss that fear as “a misconception [and] mistaken belief”.Continue reading...

Skin patch costing 39p could save lives of stroke victims, researchers say
Trials show patch significantly increases chances of survival when rapidly applied by paramedics during journey to hospitalA skin patch costing as little as 39p could revolutionisestroke treatment, significantly increasing the chances of survival, researchers have found.The patch contains glyceryl trinitrate (GTN), which lowers blood pressure and opens up blood vessels, helping reduce the damage caused in the immediate minutes and hours following a stroke.Continue reading...

The controversy over statins has revealed something: the nocebo effect is real | Ann Robinson
Just as placebos can have a positive effect, expectation of side-effects can have a negative one. That ’s why proper doctor-patient communication is so vitalStatins are back in the news;a new study shows that media-fuelled controversy among health experts has dented public confidence in the cholesterol-lowering drugs that prevent 80,000 heart attacks and strokes every year in the UK. The benefits far outweigh the harm from rare side-effects, according to a review of the evidence in the Lancet medical journal. But200,000 people stopped taking their statins in 2013 following six months of “disputed research and tendentio...

Statin side-effects down to negative expectations, not the drugs, say study
Researchers hope study will end debate around statins, which could benefit over six million UK patients who are not taking them, or take low dosagesCommon side-effects of statins are not down to the drugs, but are instead a result of patients ’ negative expectations, research suggests.Statins are typically prescribed to help lower levels of “bad cholesterol” – or low-density lipoprotein – in order to reduce the risk of a heart attack or stroke. Arecent report estimated that the drugs prevent around 80,000 such incidents a year in the UK.Continue reading...

Q & A: saturated fat, your health and what the experts say
The key points in a debate between cardiology experts over the link between fat, cholesterol and coronary diseaseWhat ’s the fuss about?A furore has blown up over whether eating saturated fat increases the risk of coronary heart disease after three cardiologists said that “the conceptual model of dietary saturated fat clogging a pipe is just plain wrong”. They also dismissed the drive for foods with lower cholesterol and the use of medications as “misguided”.Continue reading...

Lab notes: is tartan T. rex about to enter the textbooks?
The potential for amassive shakeup of the dinosaur family tree (including a possible common ancestor from Scotland) was mooted this week – will a new classification come in and overturn over a century of evolutionary assumptions? Stay tuned, dino-lovers. In the meanwhile, I may have to reverse my personal policy on our eight-legged friends with the news that and ingredient infunnel web spider venom can protect cells from being destroyed by a stroke. Alongside this is the news that a new test can predict age when Alzheimer ’s disease will appear. It’s based on 31 genetic markers could be used to calculate any individu...

Deadly spider venom could ward off stroke brain damage, say doctors
Ingredient in funnel web spider venom can protect cells from being destroyed by a stroke, even when given hours after the event, study showsDoctors have stumbled on an unlikely source for a drug to ward off brain damage caused by strokes: the venom of one of the deadliest spiders in the world.A bite from an Australian funnel web spider cankill a human in 15 minutes, but a harmless ingredient found in the venom can protect brain cells from being destroyed by a stroke, even when given hours after the event, scientists say.Continue reading...

Lab notes: what a mammoth week for science!
Yes it ’s a big story in more ways than one – a team of Harvard scientists say that scientists say they are on thebrink of being able to create a hybrid elephant-mammoth embryo. There are lots of technical and ethical concerns to address before we actually have real, live mammoths (or mammophants, as they ’re being called by some) but the idea of “de-extinctifying” something that’s been gone for 4,000 years is pretty exciting. This isn’t the only genetic engineering story in town this week, though, as amajor US report out this week has prepared ground for genetic modification of human embryos, eggs and sperm ...

In search of the stroke detector
Up to 50% of stroke diagnoses are inaccurate. What if a small biosensor could do the job precisely? Robert McCrum, who survived a ‘brain attack’ 22 years ago, traces one team’s long journey to a breakthroughStroke, or “brain attack”, is the third biggest killer in the western world, after cancer and heart failure. The life-changing effects associated with this simple, Anglo-Saxon word are readily explained: a stroke occurs when the blood supply to the brain is disrupted by a blood vessel either bursting or blocking, so that the part of the brain supplied by this blood vessel dies.The brain is a much more com...

Stroke patients in UK 'missing out on treatment for brain clots'
Thousands of patients not being offered procedure that can dramatically reduce disability after a stroke, research suggestsThousands of stroke patients in the UK may be missing out on a treatment that involves physically unplugging blood vessels in the brain, research suggests.Scientists estimate that about 9,000 patients with blood clots in the brain – a tenth of the total – could benefit from mechanical thrombectomy (MT) each year. Currently, fewer than 600 patients a year undergo the procedure.Continue reading...
