Randomized Controlled Trial Clinical Trial
Capillary leak syndrome in children with C4A-deficiency undergoing cardiac surgery with cardiopulmonary bypass: a double-blind, randomised controlled study.
Capillary leak syndrome is a life-threatening complication after cardiopulmonary bypass (CPB), with an incidence of about 4-37% in children worldwide. On the basis of previous results, we undertook a randomised controlled study to investigate the priming with plasma rich in the C4A isotype of complement component 4 on the incidence of capillary leak syndrome in children with C4A deficiency. ⋯ In paediatric patients with C4A deficiency, C4A-rich plasma priming reduces the incidence of CPB-related capillary leak syndrome by blocking the activated C4 increase and attenuating the systemic inflammatory response after CPB.

Randomized Controlled Trial Multicenter Study Clinical Trial
Postoperative radiotherapy after radical prostatectomy: a randomised controlled trial (EORTC trial 22911).
Local failure after prostatectomy can arise in patients with cancer extending beyond the capsule. We did a randomised controlled trial to compare radical prostatectomy followed by immediate external irradiation with prostatectomy alone for patients with positive surgical margin or pT3 prostate cancer. ⋯ Immediate external irradiation after radical prostatectomy improves biochemical progression-free survival and local control in patients with positive surgical margins or pT3 prostate cancer who are at high risk of progression. Further follow-up is needed to assess the effect on overall survival.

Persistent infection in resting CD4+ T cells prevents eradication of HIV-1. Since the chromatin remodeling enzyme histone deacetylase 1 (HDAC1) maintains latency of integrated HIV, we tested the ability of the HDAC inhibitor valproic acid to deplete persistent, latent infection in resting CD4+ T cells. ⋯ Combination therapy with an HDAC inhibitor and intensified HAART safely accelerates clearance of HIV from resting CD4+ T cells in vivo, suggesting a new and practical approach to eliminate HIV infection in this persistent reservoir. This finding, though not definitive, suggests that new approaches will allow the cure of HIV in the future.

Tamoxifen has been the standard adjuvant treatment for postmenopausal women with hormone-responsive early breast cancer for more than 20 years. However, the third-generation aromatase inhibitor anastrozole has proven efficacy and tolerability benefits compared with tamoxifen when used as initial adjuvant therapy. We investigate whether women who have received a period of adjuvant tamoxifen would benefit from being switched to anastrozole. ⋯ These data lend support to a switch from tamoxifen to anastrozole in patients who have completed 2 years' adjuvant tamoxifen.
