Most Americans And Canadians With HIV Diagnosed Too Late

Most Americans And Canadians With HIV Diagnosed Too Late.
Americans and Canadians infected with HIV are not getting diagnosed fast enough after exposure, resulting in a potentially toxic stoppage in lifesaving treatment, a new large study suggests. The observation stems from an scrutiny involving nearly 45000 HIV-positive patients in both countries, which focused on a key yardstick for protected system strength - CD4 cell counts - at the time each patient first place began treatment. CD4 counts measure the number of "helper" T-cells that are HIV's preferred target.

Reviewing the participants' medical records between 1997 and 2007, the span found that throughout the 10-year study period, the norm CD4 count at the time of first treatment was below the recommended level that scientists have yearn identified as the ideal starting point for medical care. "The public health implications of our findings are clear," over author Dr Richard Moore, from the Johns Hopkins University School of Medicine in Baltimore, said in a information release. "Delayed diagnosis reduces survival, and individuals enter into HIV meticulousness with lower CD4 counts than the guidelines for initiating antiretroviral therapy". A suspend in getting treatment not only increases the chance that the disease will progress, but boosts the risk of transmission.

Repeated Brain Concussion Can Lead To Disability

Repeated Brain Concussion Can Lead To Disability.
After taking a stark hit to the principal during a football game, an Indiana high school student suffered severe headaches for the next three days. Following a point CT scan that was normal, his doctor told him to time to go back on the field until he felt better. But the boy returned to practice, where he suffered a devastating understanding injury called second impact syndrome. More than six years later, Cody Lehe, now 23, is mostly wheelchair-bound and struggles with diminished screwy capacity.

Yet he's fortunate to be alive: Second effect syndrome is fatal in about 85 percent of cases. "It's a unique syndrome of wisdom injury that appears in high school and younger athletes when they have a mild concussion, and then have a more recent head impact before they're over the symptoms of their first impact. This leads to massive perceptiveness swelling almost immediately," said Dr Michael Turner, a neurosurgeon at Goodman Campbell Brain and Spine at the Indiana University School of Medicine, and co-author of a fresh report on Cody's case, published Jan. 1 in the Journal of Neurosurgery: Pediatrics.

The lawsuit study illustrates why it's so noted to prevent a second impact and give a young brain the chance to rest and recover, another proficient said. "Second impact syndrome is a very rare phenomenon. It's estimated to occur about five times a year in the country," said Kenneth Podell, a neuropsychologist and co-director of the Methodist Concussion Center in Houston.

So "What makes this bookwork unique: They're the premier ones to in point of fact have a CT scan after the first hit. What they were able to show is that the first CT scan was read as normal," said Podell, who also is a side consultant for the Houston Texans, of the NFL. "After the first concussion there was no witness of any significant injury.
