Exercise suppresses appetite by affecting appetite hormones

Tweet

BETHESDA, Md. (Dec. 11, 2008) − A vigorous 60-minute workout on a treadmill affects the release of two key appetite hormones, ghrelin and peptide YY, while 90 minutes of weight lifting affects the level of only ghrelin, according to a new study. Taken together, the research shows that aerobic exercise is better at suppressing appetite than non-aerobic exercise and provides a possible explanation for how that happens.

People who have been diagnosed with panic attacks or panic disorder have a greater risk of subsequently developing heart disease or suffering a heart attack than the normal population, with higher rates occurring in younger people, according to research published in Europe's leading cardiology journal, the European Heart Journal [1] today (Thursday 11 December).

Drug-resistant tuberculosis rife in China

Levels of drug-resistant tuberculosis (TB) in China are nearly twice the global average. Nationwide research published in the open access journal BMC Infectious Diseases has shown that almost 10% of Chinese TB cases are resistant to the most effective first-line drugs.

Living in multigenerational households triples women's heart disease risk

Tweet

Living in a household with several generations of relatives triples a woman's risk of serious heart disease, suggests research published ahead of print in the journal Heart.

The researchers assessed the long term impact on health of domestic living arrangements among almost 91,000 Japanese men and women aged between 40 and 69.

None of the study participants had been diagnosed with any serious illness, such as cancer, heart disease, or stroke at the start of the study in 1990-4.

Experienced pilots may be at risk of DNA damage from ionizing radiation

Tweet

Airline pilots who have flown for many years may be at risk of DNA damage from prolonged exposure to cosmic ionising radiation, suggests a study published ahead of print in Occupational and Environmental Medicine.

The research team compared the rate of chromosomal (DNA) abnormalities in blood samples taken from 83 airline pilots and 50 university faculty members from the same US city.

The two groups were matched for age (35 to 56), sex (male), and smoking habit (light or non-smokers). Age and smoking are known risk factors for cumulative DNA damage.

One in three UK adults will be obese by 2012

Tweet

One in three UK adults—or 13 million people—will be obese by 2012, finds research published ahead of print in the Journal of Epidemiology and Community Health.

And almost half of them will be from low income and disadvantaged communities, widening the health gap between the haves and have-nots even further, say the authors.

The researchers draw their conclusions on an analysis of annual data between 1993 and 2004 from the Health Survey for England.

Credit crunch hits cash-strapped homeowners

Tweet

Homeowners have drawn on their biggest asset, the roof over their heads, not to fund 'champagne moments' but to get through hard times; that's the finding of a preliminary study by Durham University.

Mortgage equity withdrawal is a much more popular and frequent event than previously thought. New figures show that borrowers haven't just used their housing equity to splash out on holidays or cars; struggling households have borrowed against their homes to meet their basic needs like bringing up the kids.

High phosphorus linked to coronary calcification in chronic kidney disease

Tweet

For patients with moderate chronic kidney disease (CKD), higher levels of phosphorus in the blood are associated with increased calcification of the major arteries and heart valves—which may contribute to the increased risk of cardiovascular disease in patients with CKD, reports a study in the Journal of the American Society of Nephrology (JASN).

Diabetes drug shows potential for treating one cause of chronic kidney disease

Tweet

The antidiabetes drug rosiglitazone may have the potential to protect kidney function in patients with a condition called focal segmental glomerulosclerosis (FSGS), according to a study appearing in the January 2009 issue of the Clinical Journal of the American Society Nephrology (CJASN). The phase I clinical findings indicate that the drug warrants further study in phase II and phase III trials.

Type 1 diabetes and celiac disease linked

Type 1 (juvenile) diabetes and celiac disease appear to share a common genetic origin, scientists at the University of Cambridge and Barts and The London School of Medicine and Dentistry, have confirmed.
