Brody, M.D., Ph.D.: Detection of Blast-Related Traumatic Human brain Damage in U.S. Military Personnel In the current wars in Afghanistan and Iraq, the number of blast-related traumatic brain injuries could be as high as 320,000.3,4 No human being autopsy studies conducted by using current immunohistochemical methods5,6 have been published.7,8 Computer simulations of the consequences of blast-induced pressure waves on the mind claim that coup and contrecoup areas could be at the mercy of high stresses.9,10 Simulations also claim that the orbitofrontal regions and the posterior fossa may sustain intense stresses independently of the subject’s head orientation in accordance with the blast.10 Findings that are consistent with this view include a positron-emission tomographic study showing decreased cerebellar basal glucose metabolism11 and a case survey documenting a lesion in cerebellar white matter on MRI after blast injury.12 In a swine model of experimental blast damage, traumatic axonal damage in several regions, which includes cerebellar tracts, was detected.13 We therefore hypothesized that traumatic axonal injury is a main feature of individual blast-related traumatic human brain injury.

Scher, M.D. For the COU-AA-301 Investigators: Abiraterone and Improved Survival in Metastatic Prostate Cancer For days gone by 70 years, depleting or blocking the action of androgens has been the typical of care for men with advanced prostate cancer.1 Androgen deprivation outcomes in a reduction in the concentration of prostate-particular antigen along with tumor regression and relief of symptoms generally in most patients, however the response to treatment is not durable in patients with advanced malignancy, and as time passes, PSA concentrations increase, indicating reactivated androgen-receptor signaling and a transition to a castration-resistant declare that is invariably fatal.2 Many endocrine therapies have already been evaluated in these sufferers, but non-e have prolonged survival.3 Three nonhormonal systemic approaches have been found to prolong survival: docetaxel4 as first-range and cabazitaxel5 as second-collection cytotoxic chemotherapy, and energetic cellular immunotherapy with sipuleucel-T.6 A distinctive molecular alteration described in castration-resistant prostate cancer may be the up-regulation of androgen biosynthesis enzymes, resulting in an increase in intratumoral androgen concentrations, that may exceed the known levels measured in the blood.7-9 Other alterations include overexpression of androgen receptors, and androgen-receptor mutations leading to androgen-receptor binding by additional ligands that would not stimulate the wild-type receptor.2,10 Abiraterone acetate, a prodrug of abiraterone, is a selective inhibitor of androgen biosynthesis that potently blocks cytochrome P450 c17 , a critical enzyme in testosterone synthesis, therefore blocking androgen synthesis by the adrenal testes and glands and within the prostate tumor.15-20 The most typical adverse events, which were connected with increased mineralocorticoid amounts, included hypokalemia, water retention, and hypertension; these events were abrogated by coadministering low-dose glucocorticoids largely.
