Only 135 cases of Zika virus infection have been reported in Florida as of August 10, with all but one case travel-related, compared with 470 Zika cases reported in the state during the same period in 2016. Experts attribute the decline to more aggressive mosquito control initiatives and a decrease in Zika infections in South America and the Caribbean.
Plastic surgeon Jesse Selber, who specializes in cancer reconstruction, was part of a multi-disciplinary surgery at MD Anderson Cancer Center in which tissue from a patient's twin sister was used to cover the site where a rare tumor was removed. Selber said it was one of the largest tissue transplantations on record, and while family members are not always well-matched, the twin sisters were 100% genetically compatible and identical.
Tim Anegon, who died from complications after a liver transplant, was an eye tissue donor, and his gift aided researchers studying diabetic eye disease, the leading cause of vision impairment among adults of working age. "A lot of the research being done on animal and cell models still teaches a lot, but we're missing that link in translating to the human pathology," Dr. Patrice Fort told Anegon's family during a meeting at the University of Michigan's Kellogg Eye Center.
The FDA has granted emergency use authorization for the CII-ArboViroPlex rRT-PCR test developed by researchers at Columbia University's Mailman School of Public Health. The test can detect Zika virus, chikungunya virus, West Nile virus and dengue virus.
Researchers found that the Ebola virus has the potential to replicate and spread through human retinal pigment epithelial cells, according to a study in the journal Translational Vision Science & Technology. "We speculate that infected cells activate the type 1 IFN response, which would limit spread of infection, but that these cells also restrict innate and adaptive immune responses, which otherwise would clear the virus from the eye," the study authors wrote.
Researchers identified 35 adults with Zika virus infections who were treated in Brazil for neuroinflammatory conditions, according to a study in the journal JAMA Neurology. The most common condition was Guillain-Barre syndrome, while encephalitis, transverse myelitis and chronic inflammatory demyelinating polyneuropathy were also reported.
Washington University in St. Louis researchers developed a diagnostic test for the Zika virus that uses gold nanorods on paper that change color if the blood sample contains the pathogen, also yielding results in minutes, according to a study published in the journal Advanced Biosystems. No false-positive results were generated when the investigators tested the assay on four people infected with Zika compared with blood samples from five uninfected people.
A study by Cedars-Sinai Heart Institute investigators published in the European Heart Journal found that injecting the hearts of aged rats with cardiosphere-derived cells from young rodents resulted in the rejuvenation of the heart's structure, improved heart function and function.
Baylor College of Medicine researchers are developing virus-specific cells -- including for the Epstein-Barr virus, adenoviruses, cytomegalovirus, BK virus and human herpesvirus 6 -- to treat viral infections in patients who receive hematopoietic stem cell transplants, according to a study in the Journal of Clinical Oncology. Thirty-eight patients received a single infusion, and the overall complete or partial response rate was 92%.
The 2017 AATB Annual Meeting will provide attendees with education opportunities associated with many of the tissue banking technologies and innovations that continually improve tissue banking processes. Concurrent sessions will offer professionals working in areas related to donor screening, tissue recovery, tissue processing and distribution, regulatory and reproductive tissues, many opportunities to share new ideas to further improve their tissue banking operations. Review the agenda and register today for the 2017 AATB Annual Meeting -- Oct. 3-6 Renaissance Orlando at SeaWorld, Florida!
