  volume={44}, 
  abstractNote={Depression is one of the most severe health issues of the modern medicine. One of the most troublesome symptoms of depression is pain. On the other hand, patients suffering from chronic pain problems are also often subjects of mood or anxiety disorders. There are still very little studies in the field of co-occurrence of these two symptoms and therefore there are no universal standards to deal with such cases.},
