The Reduviid Triatoma infestans is a vector for the protozoan Trypanosoma cruzi, the etiological agent of Chagas disease. The parasite must address the defense molecules and microbiota that colonize the anterior midgut of T. infestans. To obtain insight into T. cruzi - microbiota interactions in triatomine insects, we characterized a new antimicrobial product from the anterior midgut of T. infestans (TiAP) that may be involved in these relationships. The TiAP DNA fragment was cloned and expressed in a bacterial system, and the effect of the protein on bacteria and T...

PURPOSE: Providing patients with written information about totally implantable access ports (TIAPs) is recommended during the pre-implantation period to reduce anxiety and to help recalling information. No study tested the effectiveness of information about TIAP neither with oral communication nor with booklets. This study aimed at evaluating the effectiveness of an information booklet, alone or together with answers to clarification questions, both in improving patients' short- and long-time knowledge about TIAP and in decreasing patients' physiological indicators of anxiety immediately after TIAP implantation...

Percutaneous central vascular venous access to allow positioning of a totally implantable access port (TIAP) is a widely employed procedure. An open issue is the need to find an ionizing radiation free technique which allows a safe and correct positioning of the device. Echo-guided vein puncture is currently accepted as the best method for decreasing major immediate complications. We describe an entirely echo-based method for the insertion and assessment of correct placement of the totally implantable access ports (TIAP)...

REVIEW
James B Jaquith
The Inhibitor of Apoptosis Proteins (IAPs) play a critical role in the regulation of cellular apoptosis and cytokine signaling. IAP family members include XIAP, cIAP1, cIAP2, NAIP, survivin, Apollon/Bruce, ML-IAP/livin and TIAP. The IAPs have been targeted using both antisense oligonucleotides and small molecule inhibitors. Several research teams have advanced compounds that bind the highly conserved BIR3 domains of the IAPs into clinical trials, as single agents and in combination with standard of care. This patent review highlights the medicinal chemistry strategies that have been applied to the development of clinical compounds...

Totally implantable access ports (TIAPs) are generally used in oncology. Few studies have addressed complications associated with the insertion site. A total of 233 consecutive oncology patients were enrolled to receive TIAP inserts via internal jugular vein (IJV) or subclavian vein (SV). Data on clinicopathologic parameters and early/late complications were retrospectively collected. No differences were found early and late complication rates. Catheter injury was observed more frequently in the IJV group (2...

Catheter rupture after totally implantable access port (TIAP) implantation via the right internal jugular vein is thought to be very rare. We report a case of catheter rupture found 682 days after TIAP surgery in a 52-year-old woman with recurrent right breast cancer. It is possible that chronic stress at the flexure of the catheter induced by neck movements caused the catheter to rupture. Therefore, when inserting a TIAP via the right internal jugular vein, the site of venous puncture should be decided on carefully...

INTRODUCTION: Totally implantable access ports (TIAPs) are often used for patients who need permanent venous access. The primary success rate using direct open insertion is about 80 per cent, so rescue strategies are needed. This study compared the primary success rates of standard open insertion and a modified Seldinger technique. METHODS: This randomized trial recruited 164 patients scheduled for primary implantation of a TIAP and compared two interventions. The primary endpoint was the success rate of the implantation technique...
