LONDON (Reuters) – Some half a million cases of cancer a year are due to people being overweight or obese, and the problem is particularly acute in North America, the World Health Organization’s cancer research agency said on Wednesday.
In a study published in the journal The Lancet Oncology, the WHO’s International Agency for Research on Cancer (IARC) said high body mass index (BMI) has now become a major cancer risk factor, responsible for some 3.6 percent, or 481,000, of new cancer cases in 2012.
LONDON, Nov 21 (Reuters) – Saudi Arabia has not yet traced the source of a mysterious camel virus, leaving many questions about a disease that has killed 346 people in the Kingdom.
The lack of scientific evidence about how camels contract the virus, which causes an often fatal illness called Middle East Respiratory Syndrome (MERS) in people, echoes wider concerns about the threat posed to human health by animal-borne pathogens, including the Ebola virus.
LONDON, Nov 20 (Reuters) – An international team of
scientists has found it may be possible to make seasonal flu
vaccines more effective by using an idea known as “back boost”
and pre-empting flu virus evolution.
In a study published on Thursday in the journal Science, the
University of Cambridge-led team said their finding should
enable people to be immunised against future likely flu strains
as well as ones currently circulating.
LONDON, Nov 19 (Reuters) – A banking culture that implicitly
puts financial gain above all else fuels greed and dishonesty
and makes bankers more likely to cheat, according to the
findings of a scientific study.
Researchers in Switzerland studied bank workers and other
professionals in experiments in which they won more money if
they cheated, and found that bankers were more dishonest when
they were made particularly aware of their professional role.
LONDON, Nov 18 (Reuters) – A five-year, fast-track battle
against HIV could end the global threat of the AIDS epidemic by
2030, the United Nations said on Tuesday, but failing to move
quickly might allow the deadly virus to spring back.
UNAIDS said reaching its new fast-track targets would avert
nearly 28 million new human immunodeficiency virus (HIV)
infections by 2030, and effectively bring to an end the
worldwide health threat it poses.
LONDON (Reuters) – Almost 200 people have received GlaxoSmithKline’s experimental Ebola vaccine in trials in the United States, Britain, Mali and Switzerland, and the safety data so far are “very satisfactory”, scientists said on Monday.
The trials, which began just over two months ago, have been using healthy volunteers, rather than patients with Ebola, to test whether the vaccine is safe for humans.
LONDON (Reuters) – More and more infections in Europe are proving able to evade even the most powerful, last-resort antibiotics, posing an alarming threat to patient safety in the region, health officials said on Monday.
Releasing annual data on antibiotic resistant superbugs, the European Center for Disease Prevention and Control (ECDC) said bacterial infections resistant to carbapenems — a major last-line class of antibiotics used to treat hospital-acquired superbugs — are ever more common in the European Union.
LONDON (Reuters) – Progress toward wiping out measles worldwide has stalled, with deaths from the highly contagious disease rising last year and poor vaccine coverage leading to large outbreaks, the World Health Organization (WHO) said on Thursday.
More than 145,000 people died of measles in 2013, up from 122,000 in 2012, the WHO said. Epidemics in China, Congo and Nigeria contributed to this, but there were also outbreaks in the WHO’s European region, including in Georgia, Turkey and Ukraine.
LONDON (Reuters) – The rate of women dying in childbirth in West African countries hit by the Ebola epidemic is soaring, with as many as one in seven at risk of death as fear of contact with bodily fluids prevents people helping them, aid charities warned on Tuesday.
The United Nations Population Fund estimates that 800,000 women in Sierra Leone, Guinea and Liberia are due to give birth in the next 12 months.
LONDON, Nov 11 (Reuters) – British scientists say they have
found the best way yet to analyse the effects of smoking on the
brain — by taking functional magnetic resonance imaging (fMRI)
scans of people while they puff on e-cigarettes.
In a small pilot study, the researchers used electronic
cigarettes, or e-cigarettes, to mimic the behavioural aspects of
smoking tobacco cigarettes, and say future studies could help
scientists understand why smoking is so addictive.
