Quercetin intake and the incidence of cerebrovascular disease

Article Abstract:

The link between intake of antioxidant flavonoid quercetin and incidences of cerebrovascular disease (CVA) was studied. Intake of apples is thought to be linked to a decreased risk of thrombotic stroke, but this link is not due to the presence of quercetin.

Rheumatoid factor, chronic arthritis and mortality

Article Abstract:

Patients with arthritis who carry the rheumatoid factor (RF) or those who test positive for RF but do not have arthritis (false positive) may have shorter life expectancies than the general population. RF is an antibody frequently found in the blood of adult patients with rheumatoid arthritis. Doctors performed a series of diagnostic tests, including RF screening, on 3,434 volunteers identified with muscle or bone diseases. They followed the group over a period of 13 to 15 years and recorded dates and causes of death for the participants. More participants with a positive or false positive RF test died during this time period as compared to the whole group. There was a higher risk of death due to heart disease in participants with a false positive RF test. There was no correlation between life expectancy and a negative RF test in participants with arthritis.

Serum androgen-anabolic hormones and the risk of rheumatoid arthritis

Article Abstract:

Serum androgen-anabolic hormones do not appear to increase the risk of rheumatoid arthritis (RA). Researchers measured hormone levels in 19,072 healthy volunteers in Finland, 116 of whom ultimately developed RA. Average testosterone and dehydroepiandrosterone sulphate (DHEAS) levels were no different among those with and without RA. Analysis of rheumatoid factor status or menopause status subgroups also revealed no hormonal differences related to RA.
