Staph bacteria becoming stronger, harder to treat, researchers say
WASHINGTON A strain of Staphylococcus bacteria resistant to antibiotics is becoming harder to treat, doctors said Monday.
Previously, drug-resistant strain, known as methicillin-resistant Staphylococcus aureas, was a problem in hospitals, but they are becoming a more serious problem among sports teams and in schools.
An estimated 20,000 people die from MRSA infections each year, and 75,000 more have serious infections. The bacteria often don’t cause symptoms when carried in the skin or nose, but can become deadly if they enter the bloodstream or internal organs, possibly causing pneumonia or tissue necrosis.
Rheumatoid arthritis drugs don’t affect cancer risk, researchers find
CHICAGO Spanish researchers have found that drugs for rheumatoid arthritis called TNF blockers don’t appear to increase the risk of cancer, the researchers announced Saturday.
The drugs block a protein called the tumor necrosis factor, which is part of the immune system and is linked to arthritic inflammation. Some studies have shown that they increase the risk of cancer because they suppress the immune system, but the researchers did not find a statistical difference between the two groups of patients studied.
The research included one group of 4,500 people who took TNF blockers between 2001 and 2007, and another that included data from between 1999 and 2005 from almost 800 people who did not take the drugs.
FDA approves Barr extended-cycle oral contraceptive
MONTVALE, N.J. The Food and Drug Administration has approved a Barr Pharmaceuticals subsidiary’s application for a new oral contraceptive, Barr said Monday.
The FDA approved Duramed Pharmaceuticals’ drug LoSeasonique (levonorgestrel/ethinyl estradiol tablets and ethynyl estradiol tablets).
Barr said the drug is the first lower-dose, extended-cycle oral contraceptive. Under the extended-cycle regimen, women take combination tablets containing 0.1 mg of levonorgestrel and 0.02 mg of ethinyl estradiol for 84 consecutive days, followed by tablets containing 0.01 mg of ethinyl estradiol for seven days. The regimen is designed to reduce the number of withdrawal bleeding periods from 13 to four per year.
“As a leader in women’s health, Duramed is committed to continuing to develop new products that provide women a choice as they discuss birth control options with their healthcare providers,” Duramed chief executive officer Fred Wilkinson said.
