This finding calls for a profound revision of our notion about CA-MRSA pathogenesis at the molecular level and has important implications for design of therapeutics directed against CA-MRSA.”
“Purpose: Salvage radiotherapy (SRT) after radical prostatectomy can potentially eradicate residual microscopic disease. Defining the optimal patient and treatment factors is essential and is particularly relevant within the context of adjuvant

vs early vs delayed postoperative radiotherapy (RT).\n\nMethods and Materials: A systematic review of all published SRT studies was performed to identify the pathologic, clinical, and treatment factors associated with relapse-free survival (RFS) after SRT. A total of 41 studies encompassing 5597 patients satisfied the study entry criteria. Radiobiologic interpretation of biochemical tumor control was used to provide the framework for the observed relationships.\n\nResults: LY2603618 Prostate-specific antigen (PSA) level before SRT (P < .0001) and RT dose (P = .0052) had a significant and independent Bafilomycin A1 chemical structure association with RFS. There was an average 2.6% loss of RFS for each incremental 0.1 ng/mL PSA at the time of SRT (95% CI, similar to 2.2-3.1). With a PSA level of 0.2 ng/mL or less before SRT, the RFS approached 64%. The dose for salvage RT in the range of 60-70 Gy seemed to be on the

steep part of the sigmoidal dose-response curve, with a dose of 70 Gy achieving 54% RFS compared with only 34% for 60 Gy. There was a 2% improvement in RFS for each additional Gy (95% CI, similar to 0.9-3.2). The observed dose-response was less robust on sensitivity analysis.\n\nConclusions: This study provides Level 2a evidence for initiating SRT at the lowest possible PSA. Dose escalation is also suggested by the data.

Progressively better tumor control rates with SRT after radical prostatectomy are achieved with a lower PSA at initiation and with a higher RT dose. Early salvage RT may be an equivalent strategy to adjuvant RT. PDGFR inhibitor (C) 2012 Elsevier Inc.”
“Background: Interleukin-18 (IL-18) plays an important role in mediating cytokine cascade leading to coronary artery lesions (CALs) in Kawasaki disease (KM. However, our research suggested that the literature regarding IL-18 and KID is limited. Consequently, this study aimed to evaluate the correlation between IL-18 and CALs in patients with KD.\n\nMethods: In this prospective study of 14 children with KD (seven without and seven with CALs in the acute phase), we obtained patient measurements of a series of serum IL-18 levels in the acute, subacute, and convalescent phases. Serum IL-18 levels were measured with a Bio-Plex cytokine assay. Control samples were obtained from 18 febrile children with viral infection.\n\nResults: Compared with febrile controls, patients with acute-stage CALs [postintravenous immunoglobulin (post-IVIG) period] had a significantly higher IL-18 level (88.4 +/- 20.7 vs 56.0 +/- 35.0 pg/mL, p = 0.006).
