A bacterium, virus or fungus can enter the joint and trigger inflammation. Examples of organisms that can infect joints are salmonella and shigella (food poisoning or contamination), chlamydia and gonorrhea (sexually transmitted diseases) and hepatitis C (a blood-to-blood infection, often through shared needles or transfusions). In many cases, timely treatment with antibiotics may clear the joint infection, but sometimes the arthritis becomes chronic.
The three most common childhood cancers are leukemia (34%), brain tumors (23%) and lymphomas (12%). In the United States cancer affects about 1 in 285 children. Rates of childhood cancer increased by 0.6% per year between 1975 and 2002 in the United States and by 1.1% per year between 1978 and 1997 in Europe. Death from childhood cancer decreased by half between 1975 and 2010 in the United States.
In 2017, 425 million people had diabetes worldwide, up from an estimated 382 million people in 2013 and from 108 million in 1980. Accounting for the shifting age structure of the global population, the prevalence of diabetes is 8.8% among adults, nearly double the rate of 4.7% in 1980.  Type 2 makes up about 90% of the cases. Some data indicate rates are roughly equal in women and men, but male excess in diabetes has been found in many populations with higher type 2 incidence, possibly due to sex-related differences in insulin sensitivity, consequences of obesity and regional body fat deposition, and other contributing factors such as high blood pressure, tobacco smoking, and alcohol intake.
Cannabidiol (CBD) is one of dozens of non-psychoactive cannabinoids found in the hemp plant. Cannabidiol, and all the other cannabinoids, were patented by the United States Government in 2003 as neuroprotectants and antioxidants (Patent No. 6,630,507). Cannabinoids are characterized by their ability to act on the cannabinoid receptors that are found throughout the body. CBD and other cannabinoids are naturally occurring compounds that display potent anti-inflammatory and pain-relieving properties. They can promote the body’s healthy regulation of the central nervous, immune, and endocannabinoid systems.
