Test could give two-year warning for Alzheimer'sMon, 09 Dec 2013 10:50:00 GMT
"New test can give two years' warning of Alzheimer's," reports the Mail Online. The news comes from a small Canadian study that found that a specific change in brain activity seen on MRI testing, combined with certain memory difficulties, was 87.5% accurate at predicting the development of Alzheimer's disease.
The study looked at people with a condition known as mild cognitive impairment (MCI). MCI describes a range of symptoms that impact on cognition and memory, but not to such an extent that it seriously affects a person's day to day life. Some people with MCI will go on to develop Alzheimer's, although it is currently difficult to identify those who would benefit from treatment.'Safe' levels of air pollution could still be harmfulMon, 09 Dec 2013 09:53:00 GMT
“EU air quality rules are still too lax to protect us from pollution,” The Independent reports. It says that air quality regulations may not be sufficient to protect people from harmful sooty particles in traffic and factory fumes.
Pollutants are measured using a system known as particulate matter or PM, based on the size of the individual element; this is measured in micrometres. As a general rule, the lower the PM, the more dangerous the pollutant is, as very small particles are more likely to bypass the body’s defences and potentially cause lung and heart problems.Study questions role of vitamin D in diseaseFri, 06 Dec 2013 09:29:00 GMT
"Doubt cast on vitamin D's role against disease," reports BBC News. The news come from a study summarising a large body of evidence from the best kind of trials – randomised controlled trials (RCTs).
The results of these trials showed that vitamin D supplements didn't appear to help prevent many diseases, including cancer and cardiovascular disease. Importantly, these trials did not cover – so do not apply to – diseases affecting the bones.Number of teen mothers falls by 8% in a yearFri, 06 Dec 2013 09:23:00 GMT
BBC News and the Metro both covered new official statistics on births in England between April 2012 and March 2013.
The detailed data, on all births in NHS hospitals in England during the last year, showed deliveries for teenage mothers (ages 13 to 19) had fallen 8.4% on the previous year and revealed huge differences in birth rates linked to deprivation.UK cancer survival rates below European averageThu, 05 Dec 2013 11:00:00 GMT
“Cancer survival in Britain the worst in Europe,” The Daily Telegraph reports.
This and many other similar headlines are prompted by a major new study on cancer survival rates in Europe from 1997 to 2007.'20 classrooms of kids' a day take up smokingThu, 05 Dec 2013 09:44:00 GMT
"The equivalent of 20 classrooms-full of children take up smoking every day in the UK," reports The Independent. This disturbing headline comes from estimates of the number of children between the ages of 11 and 15 who start smoking each day. The estimates are based on a major survey of secondary schoolchildren in England.
Approximately 567 out of 6,519 children in this age group were estimated to start smoking each day, which equates to more than 200,000 a year. While this figure is high, the true figures may be higher as children may be reluctant to report their smoking, particularly when at school.Today's mums 'less active' than mothers in the 1960sWed, 04 Dec 2013 10:30:00 GMT
"Mothers today need around 200 fewer calories a day than those of previous generations because they spend more time watching TV," the Daily Mail has reported. Its story is based on research looking at the physical activity levels of American mothers over the last 45 years.
Among a host of results, the study found that in 2010 mothers with younger children spent nearly 14 less hours a week on physical activity than in 1965, and expended an average of nearly 1,600 fewer calories a week. Instead, mothers spent more time on sedentary activities such as "screen-based media use", which includes time spent watching TV and using smartphones.Study may bust myth of 'fat and fit' healthy obesityWed, 04 Dec 2013 00:00:00 GMT
The Times has reported that the idea you can be ‘fat and fit’ is “a big fat myth”.
The term ‘fat and fit’ refers to the hypothesis that if you are obese, but all other metabolic factors such as blood pressure, are within recommended limits, then your obesity will not have a harmful effect on your health.New test shows if DCIS breast cancer will spreadTue, 03 Dec 2013 11:30:00 GMT
"New test for breast cancer that could spare thousands needless treatment,” the Daily Mail reports. Researchers have identified a molecule – integrin ?v?6 – that appears to be associated with the development of invasive breast cancer.
The research investigated an early type of breast cancer called ductal carcinoma in situ (DCIS). DCIS means there are abnormal cancer cells in the breast ducts, but the cancer has not yet spread.Sperm blocking study brings 'male pill' closerTue, 03 Dec 2013 10:30:00 GMT
"Researchers announce discovery of proteins that can be blocked to prevent the launch of sperm cells during ejaculation," The Guardian reports. The paper explains that if drugs can be found that turn off these proteins, a male contraceptive pill could become a reality.
However, the news is based on a study on mice in a laboratory. In the study, the male mice were bred to have two genes that were "turned off", preventing the production of two proteins associated with sperm ejaculation.Last updated: 15 December 2009
