The 6 things most likely to send you to an early grave

Sitting too long and having lie-ins could take years off your life, new research suggests.

Scientists have drawn up a new list of the factors that raise a person’s risk of an early grave. 

Previous research has identified important risk factors such as alcohol consumption, poor diet, inactivity and smoking which reduce lifespan.

A higher rating in each of the six categories leads participants to being given a higher risk.

A person who has all six bad habits is more than five times as likely to die during a six-year period as one who is very clean-living.

Heart disease patients who sit a lot have worse health even if they exercise

Patients with heart disease who sit a lot have worse health even if they exercise, reveals research.

"Get up and move every 30 minutes to improve health."

"Limiting the amount of time we spend sitting may be as important as the amount we exercise," said lead author Dr Stephanie Prince. "Sitting, watching TV, working at a computer and driving in a car are all sedentary behaviors and we need to take breaks from them."

Previous research has shown that being sedentary increases the risk of cardiovascular disease but until now its effect on patients with established heart disease was unknown.

Resuming exercise soon after heart attack can improve heart recovery

 

Exercise promotes heart health. However, many lifestyle factors cause heart disease, and regular activity may not be enough to prevent heart attacks. A new study expands on the heart benefits of exercise, investigating whether regular exercise still helps the heart even after a heart attack occurs.

After a heart attack, restoring blood flow to the oxygen-starved region of the heart is not enough to make the heart function normally again. The affected area scars and thins, and the heart changes structurally. Because of the remodeling and loss of working heart muscle, heart attack survivors can develop other heart complications. A team of researchers investigated whether aerobic exercise could reduce the scarring, thinning and structural changes, improving recovery success in physically active individuals.

New treatment options, better hope of preventing vision loss from diabetes

 

Diabetic retinopathy is the leading cause of vision loss and blindness. An advanced stage, called proliferative diabetic retinopathy, occurs when abnormal blood vessels grow near the retina, the light-sensitive tissue at the back of the eye. These new vessels can leak blood, which can obscure vision and damage the retina. Lucentis is one of several drugs called VEGF inhibitors that can block this process.

In the new study, Lucentis was compared to scatter laser therapy (or panretinal photocoagulation), which has been the standard treatment for proliferative diabetic retinopathy since the 1970s. Although laser therapy is effective in improving central vision, it can cause decreased night and side vision. The study found that Lucentis produced more improvement in central vision and little change in side vision when compared to laser therapy.

Blood sample new way of detecting cancer

A new RNA test of blood platelets can be used to detect, classify and pinpoint the location of cancer by analysing a sample equivalent to one drop of blood. Using this new method for blood-based RNA tests of blood platelets, researchers have been able to identify cancer with 96 per cent accuracy. This according to a study.

"Being able to detect cancer at an early stage is vital. We have studied how a whole new blood-based method of biopsy can be used to detect cancer, which in the future renders an invasive cell tissue sample unnecessary in diagnosing lung cancer, for instance. In the study, nearly all forms of cancer were identified, which proves that blood-based biopsies have an immense potential to improve early detection of cancer," according to Jonas Nilsson, cancer researcher.

In the study, researchers have investigated how a new method of blood-based RNA tests of the part of the blood called platelets could be used in detecting and classifying cancer.

The results show that blood platelets could constitute a complete and easily accessible blood-based source for sampling and hence be used in diagnosing cancer as well as in the choice of treatment method.
