Issues on cholesterol: diet, statins and genetics

Genetic lipoprotein disorders are frequently seen in patients with premature coronary artery disease (CAD). An example of strong genetic predisposition is the disorder: familial hypercholesterolemia, where a single gene defect (the low density lipoprotein receptor) contributes to most of the familial expression of CAD.

New genetic link to inflammatory bowel diseases discovered

A study which entailed scientists trawling through the genetic code of thousands of people, has revealed two new genes involved in childhood inflammatory bowel disease, a painful condition that includes Crohn's disease and ulcerative colitis (UC).

Genetic link discovered to common form of leukaemia

Researchers in the UK have discovered a genetic link to a common form of leukaemia.

Discovery of tumour growth enzyme could lead to new cancer drugs

Scientists say a landmark study has revealed an enzyme which is vital to the growth of many cancers.

Faster heart rate linked to increased heart attack risk

A long-term study has revealed a link between a faster heart rate and the risk of a heart attack and the researchers say that heart disease patients with a pulse of more than 70 beats a minute are most at risk.

Best use of drug-eluting stents: When should they be avoided?

Compared with bare metal stents, drug-eluting stents substantially reduce the risk of angiographic and clinical recurrence but do not affect mortality or the short term or long term risk of myocardial infarction.

DES in diabetic patients

The issue of using or not using DES in patients with diabetes will be debated between Professor Wijns, who discourages DES and Professor Silber, who feels that they should be used.

Genetic testing for sudden cardiac death

Sudden Cardiac Death (SCD) is a major contributor to mortality in industrialized nations, affecting around 500,000 individuals annually in the Western World, and causing more deaths than AIDS, lung and breast cancer and stroke together.

Positive exercise testing in athletes: What does that mean?

Sudden cardiac death (SCD) during sports activity is an uncommon, but catastrophic event. Different efforts to reduce the risk of SCD related to sports have been undertaken. What is the role of the exercise test in this context? What does a positive exercise test mean?

Should we use echocardiography to screen young athletes?

Sudden and unexpected deaths in young competitive athletes are uncommon but highly visible events, which raise concern and ethical issues in both the lay public and medical community. Which is the best strategy to timely identify individuals with cardiac disease responsible for sudden death (primarily, HCM) is largely debated. Namely, the extent to which sophisticated testing, such as echocardiography, is needed is still undefined.

TIME-CHF Trial: Elderly HF patients do not benefit from intensive medical therapy

Intensified, BNP-guided therapy was no more effective than a standard, symptom-guided approach in elderly heart failure patients in reducing the number of deaths and all-cause hospitalisations. However, the response to this intervention differed significantly between patients aged 60-74 years and those aged ¡Ý75 years. This indicates the need for specific data in this large subset of very old heart failure patients who have been largely excluded from large treatment trials.

Sports-related sudden cardiac death is reduced by pre-participation cardiovascular screening

Young competitive athletes are perceived by the general population to be the healthiest members of society. The possibility that highly trained athletes may have a potentially serious cardiac condition that can predispose to life-threatening tachyarrhythmias or sudden cardiac death seems paradoxical.

Study points to one cause of higher rates of transplanted kidney rejection in blacks

A Johns Hopkins research team reports it may have an explanation for at least some of the higher organ rejection rates seen among black - as compared to white - kidney transplant recipients.

Blood vessel cells are instructed to form tube-like structures

How do blood vessel cells understand that they should organise themselves in tubes and not in layers? A research group from Uppsala University shows for the first time that a special type of "instructor" molecule is needed to accomplish this. These findings, published in the scientific journal Blood, might be an important step towards using stem cells to build new organs.

Researchers devise means to create blood by discovering earliest form of human blood stem cells

Johns Hopkins researchers have discovered the earliest form of human blood stem cells and deciphered the mechanism by which these embryonic stem cells replicate and grow. They also found a surprising biological marker that pinpoints these stem cells, which serve as the progenitors for red blood cells and lymphocytes.

Low levels of 'brain derived neurotrophic factor' may lead to obesity

A brain chemical that plays a role in long term memory also appears to be involved in regulating how much people eat and their likelihood of becoming obese, according to a National Institutes of Health study of a rare genetic condition.

Antidepressants need new nerve cells to be effective

Researchers at UT Southwestern Medical Center have discovered in mice that the brain must create new nerve cells for either exercise or antidepressants to reduce depression-like behavior.

Why transplanted insulin cells die

New research can enhance survival of islets transplants and improve treatment of type 1 diabetes. Transplantation of insulin-producing cell islets, so-called islets of langerhans is an appealing strategy for treatment of type 1 diabetes. But it turns out that these are short-lived, and the procedure needs to be repeated.

New role for Natural Killer cells

Scientists at the University of York have discovered a new role for a population of white blood cells, which may lead to improved treatments for chronic infections and cancer.
