Post-traumatic stress disorder (PTSD) is an extreme form of anxiety caused by the laying down of bad memories when someone is involved in a threatening situation. A new treatment has been developed for people to write about their experience, and feelings about the memory. Having your blood pressure checked at the doctor's or hospital is a health care basic. A recent trial has found a significant and possibly unexpected source or error: the size of the cuff, relative to the thinness or thickness of your upper arm. For people with cancer, being offered a place in a clinical trial can provide hope of a better outcome, but trial participants are far less likely to be from culturally and linguistically diverse backgrounds than the general population.
