Most Salmonella infections in Denmark contracted abroad
Date: Jul-31-2013These are some of the findings presented in the annual report on the occurrence of diseases that can be transmitted to humans from animal and food. The report is prepared by the Danish Zoonosis Centre at the National Food Institute, Technical University of Denmark in collaboration with Statens Serum Institut and the Danish Veterinary and Food Administration. In 2012, 1,198 Danes were registered with a Salmonella infection, which corresponds to 21 cases per 100,000 citizens. It is a little more than the record-low incidence in 2011...
How do you know that something you cannot see is still present?
Date: Jul-31-2013How do you know that the cookies are still there although they have been placed out of your sight into the drawer? How do you know when and where a car that has driven into a tunnel will reappear? The ability to represent and to track the trajectory of objects, which are temporally out of sight, is highly important in many aspects but is also cognitively demanding. Alice Auersperg and her team from the University of Vienna and Oxford show that "object permanence" abilities in a cockatoo levels apes and four year old human toddlers...
Researchers urge review of health system-wide pediatric injury training, triaging and prevention efforts
Date: Jul-31-2013New research from The Center for Injury Research and Prevention at The Children's Hospital of Philadelphia (CHOP), signals that emergency and outpatient healthcare providers may need to prepare for higher demand for treatment among younger patients with mild and moderate injuries. As federal and state policies encouraging people to be covered by health insurance go into effect, researchers estimate the potential for more than 730,000 additional medically attended injuries annually, or a 6.1 percent increase if all currently uninsured children and young adults (ages 0-26) become insured...
Reducing head hits in youth football by limiting contact in practice
Date: Jul-31-2013Less contact during practice could mean a lot less exposure to head injuries for young football players, according to researchers at Wake Forest Baptist Medical Center and Virginia Tech. Their study of 50 youth-league players ages 9 to 12 -- the largest ever conducted to measure the effects of head impacts in youth football -- found that contact in practice, not games, was the most significant variable when the number and force of head hits incurred over the course of a season were measured...
Most young Swiss cannabis smokers are aware of the health risks
Date: Jul-31-201391 percent of on average 20-year-old Swiss men drink alcohol, almost half of whom drink six beverages or more in a row and are thus at-risk consumers. 44 percent of Swiss men smoke tobacco, the majority of whom are at-risk consumers - they smoke at least once a day. 36 percent of young adults smoke cannabis, whereby over half are at-risk consumers, using the drug at least twice a week...
Fresh fuel reignites Asperger's debate
Date: Jul-30-2013Children with Asperger's Syndrome have different electroencephalography (EEG) patterns to children with autism, reveals a study in the open access journal BMC Medicine With distinct neurophysiology, the study pours fresh fuel on the on-going debate about how Asperger's should be classified. People with Asperger's syndrome experience social difficulties, and display restricted and repetitive behavioural patterns and interests...
Increased fluctuation in blood pressure over time is linked to impaired cognitive function in older people
Date: Jul-30-2013Higher variability in visit-to-visit blood pressure readings, independent of average blood pressure, could be related to impaired cognitive function in old age in those already at high risk of cardiovascular disease, suggests a paper published on bmj.com. There is increasing evidence that vascular factors contribute in development and progression of dementia. This is of special interest as cardiovascular factors may be amendable and thus potential targets to reduce cognitive decline and the incidence of dementia...
Cardiovascular risk in type 2 diabetics with dangerously low blood sugar levels
Date: Jul-30-2013Type 2 diabetics who have severe hypoglycaemia are at higher risk of cardiovascular disease, a paper published on bmj.com suggests. Severe hypoglycaemia is a condition where there is an abnormally low content of sugar in the blood. It is often classed as a medical emergency. Severe hypoglycaemia is a potential risk factor for cardiovascular disease in patients with type 2 diabetes and recent clinical trials have failed to demonstrate a beneficial effect of intensive glucose control on overall CVD events...
New definition of chronic kidney disease labels 1 in 8 adults as sick
Date: Jul-30-2013A new definition of chronic kidney disease labels over 1 in 8 adults and around half of people over 70 years of age as having the disease. Yet low rates of kidney failure suggest many of those diagnosed will never progress to severe disease. On bmj.com, Ray Moynihan and colleagues argue this is evidence of overdiagnosis. They call for a re-examination of the definition and urge clinicians to be cautious about labelling patients, particularly older people. This article is the second of a series looking at the risks and harms of overdiagnosis in a range of common conditions...
Technology in kids' bedrooms disrupts sleep patterns
Date: Jul-30-2013Media technology in children's bedrooms such as TVs and computers can disrupt their sleep patterns, according to a study published in the journal BMC Public Health. Researchers from Helsinki, Finland, conducted the first long-term study to find out whether electronic media use and electronic media presence in a child's bedroom predicted or changed sleep habits. Participants in the study analyzed schoolchildren aged 10 and 11 years old from 27 schools across the Scandinavian country...
