Study finds high graft survival rate after osteochondral transplant | Study examines latissimus dorsi tendon transfer against rotator cuff tear | CDC updates guidelines on diagnostic testing for Zika virus
The 10-year rate of osteochondral allograft survivorship among patients treated for articular cartilage damage of the femoral trochlea was 91.7%, according to a study in the American Journal of Sports Medicine. At the most recent follow-up, researchers found an 89% satisfaction rate.
An 86-patient study found that arthroscopic-assisted latissimus dorsi tendon transfer could result in pain relief and functional improvements among patients with irreparable, posterosuperior massive rotator cuff tears. The researchers assessed patients using Constant and Murley scores.
The CDC has found that the Zika virus infection remains detectable longer in the urine than in blood, prompting the agency to update its diagnostic testing guidelines for the virus. The CDC is recommending that polymerase chain reaction testing be conducted on urine collected less than two weeks following the start of symptoms.
The Senate voted 68 to 29 on Tuesday in favor of $1.1 billion in emergency funding to fight the Zika virus. The White House has requested $1.9 billion, while House Republicans have proposed moving $622 million from other initiatives.
The yellow fever mosquito (Aedes aegypti) is known to spread the Zika virus, but new research suggests the Asian tiger mosquito (Aedes albopictus) may also transmit the pathogen. Tests indicate the virus is present in the species and can multiply in its salivary glands, but no data definitively show the virus spreading from mosquito to people. Researchers say it's critical to determine the role of the tiger mosquito in Zika transmission to forecast how the disease will spread in the Americas.
Puerto Rico has reported the first known case of Zika virus-related microcephaly involving an infection acquired in the US, according to health officials. The pregnancy resulted in a miscarriage in the second trimester, and the CDC confirmed the presence of the virus in brain tissue.
The Health Research Council of New Zealand awarded about $46,800 to a researcher from Auckland University's School of Biological Sciences for work on the development of a biomaterial based on proteins from fish eyes for use in human corneal replacements.
