The original definitions of sepsis and related conditions (SIRS, severe sepsis and septic shock) are now more than 20 years old (Sepsis- 1 originated from the ACCP/SCCM consensus meeting in 1991 and Sepsis 2 from 2001)
Lifting something heavy. This caution is really for women who can cause a placental tear in the second or third trimester. This does not necessarily mean a miscarriage, and usually if you feel terrible pains later, it just means that you strained one of the round ligaments holding your uterus in place. A little rest will be all that is needed.
Improper or heavy lifting is a common cause of back pain, but it doesn't only happen to people who lift heavy boxes on the job. Carrying a bulky laptop bag, suitcase, camera, or a load of groceries can also cause a strain on your back.
