ADHD linked to social and economic status

ADHD linked to social and economic disadvantage — Scientists have found evidence of a link between social and economic status and childhood attention deficit disorder in the UK – Scientists have found evidence of a link between social and economic status and childhood attention deficit disorder (ADHD) in the UK. A team led by the University of Exeter Medical School analysed data from the Millennium Cohort Study, a database of more than 19,500 UK children born between 2000 and 2002.

Blood stem cells longevity mechanism discovered

Mechanism Behind Blood Stem Cells’ Longevity Discovered – The blood stem cells that live in bone marrow are at the top of a complex family tree. Such stem cells split and divide down various pathways that ultimately produce red cells, white cells and platelets. These “daughter” cells must be produced at a rate of about one million per second to constantly replenish the body’s blood supply.

Women specific chest pain symptoms not enough in heart attack diagnosis

Findings Not Supportive of Women-Specific Chest Pain Symptoms in Heart Attack Diagnosis – Using chest pain characteristics (CPCs) specific to women in the early diagnosis of acute myocardial infarction (AMI, heart attack) in the emergency department does not seem to be supported by the findings of a study published by JAMA.

High salt in some medicines may increase heart attack and stroke risk

High salt levels in common medicines put patients at increased risk of cardiovascular events — Researchers call for salt content of medicines to be labeled in same way as foods – Taking the maximum daily dose of some medicines would exceed the recommended daily limits for sodium, without any additional dietary intake. Public should be warned about the potential dangers of high sodium intake from prescribed medicines, reveals new study.

Actual pandemic flu death toll was much higher in 2009

2009 Pandemic Flu Death Toll Much Higher Than Official Worldwide Estimates – A research team consisting of more than 60 collaborators in 26 countries has estimated the global death toll from the 2009 outbreak of the H1N1 virus to be 10 times higher than the World Health Organization’s count, which was based on laboratory-confirmed cases of this flu.

Regular physical activity in later life boosts healthy aging sevenfold

Regular physical activity in later life boosts likelihood of ‘healthy aging’ up to sevenfold — Helps stave off major ill health and dementia even for those getting started relatively late – It’s never too late to get physically active, with even those starting relatively late in life reaping significant health benefits, reveals researchers. Four years of sustained regular physical activity boosted the likelihood of healthy ageing sevenfold compared with consistent inactivity.

New therapeutic targets for treating Parkinson’s disease

Gene-silencing study finds new targets for Parkinson’s disease — NIH study sheds light on treatment of related disorders – Scientists at the National Institutes of Health have used RNA interference (RNAi) technology to reveal dozens of genes which may represent new therapeutic targets for treating Parkinson’s disease. The findings also may be relevant to several diseases caused by damage to mitochondria, the biological power plants found in cells throughout the body.

Nut consumption lowers risk of diseases

Large study links nut consumption to reduced death rate — Research also shows people who eat nuts weigh less – In the largest study of its kind, people who ate a daily handful of nuts were 20 percent less likely to die from any cause over a 30-year period than were those who didn’t consume nuts, say scientists from Dana-Farber Cancer Institute, Brigham and Women’s Hospital, and the Harvard School of Public Health.
