Cardiac risks higher in patients with arthritis, psoriasis

arthritis painA higher cardiac event risk was thought to exist in patients suffering from rheumatoid arthritis, but little was known about the link between psoriatic arthritis and heart disease. Psoriasis is a chronic auto-immune disorder that affects people in middle age worldwide. This disorder has affected more than 7.5 million people as per the data shared by National Psoriasis Foundation.

Physical Activity May Treat Depression

depressionStudies say that today depression is a mental illness which affects about one in ten people. Depression is a condition where a person feels useless, hopeless and extremely sad. This can happen without any apparent reason. The episodes last for long and occur frequently to the point that it affects the daily functioning of the person. Traditional treatment is performed with anti-depressants and psychotherapy.

Recent studies conducted by the University of Bern show that regular physical exercise can help alleviate symptoms of depression, anxiety and stress. Physical activity is known to be beneficial for overall health and prevention of cardiac diseases. The basic cause of depression is the deficiency of a certain chemical known as serotonin. Serotonin is an important chemical in the brain which is responsible for a variety of functions related to mood, sleep and appetite. Thereby, a deficiency of serotonin leads to depression, but what causes this deficiency is yet unknown.

Implants for the Future

knee implantThe world health organization (WHO) has stated that by 2050 the largest population of the world will comprise people above the age of 50. This tells us the gravity and vastness of the age related issues that will be encountered in the near future. The commonest of these age related problems are joint and bone disorders which call for surgeries like knee replacement and hip replacement to promise a better quality life to the elderly. However, the difficult part is recovery from these major surgeries with quick bone healing.

A group of scientists from the University of Malaya and four other universities in the US have found a technique of developing better biomedical implants to accelerate bone healing. An implant is a medical device made of a biomedical material that is fitted into the body to act as a missing biological structure. A study published on the front cover of the July issue of Applied Surface Science, reveals that the researchers have been successful in making new biomedical implants. These use magnesium coatings that do not crack, reducing the chance of post surgery complications.
