Subclinical levels of polysubstance use are a prevalent and understudied phenomenon. Alcohol is a substance commonly co-used with other substances of other drug classes. These studies sought to determine the consumption effects of combining alcohol drinking and methamphetamine (MA) self-administration. Male alcohol-preferring P rats had continuous access to a two-bottle alcohol drinking procedure in the home cage. Control rats remained alcohol naïve. Rats were also surgically implanted with intra-jugular catheters and trained to self-administer saline (control) or MA in daily 2-hour sessions...

BACKGROUND: In patients with severe pulmonary arterial hypertension, subcutaneous or catheter-based intravenous application of prostanoids carries a risk of local side effects or systemic infections, which limits their use and acceptance. Recently, a fully implantable pump for continuous application of intravenous treprostinil was approved in Germany. However, surgery is a major risk for patients with severe pulmonary arterial hypertension. The purpose of this study was to investigate the safety of a fully implantable pump inserted under local or general anesthesia in patients with severe pulmonary hypertension...

BACKGROUND: Totally implantable venous access ports (TIVAPs) are used for prolonged central venous access, allowing the infusion of chemotherapy and other fluids and improving the quality of life of children with cancer. TIVAPs were developed to reduce the infection rates associated with central venous catheters; however, infectious events remain common and have not been fully investigated in pediatric oncology patients. PROCEDURE: A retrospective cohort was formed to investigate risk factors for central line-associated bloodstream infection (CLABSI) in pediatric cancer patients...

BACKGROUND: A totally implantable venous access device (TIVAD) provides reliable, long-term vascular access and improves patients' quality of life. The wide use of TIVADs is associated with important complications. A meta-analysis was undertaken to compare the internal jugular vein (IJV) with the subclavian vein (SCV) as the percutaneous access site for TIVAD to determine whether IJV has any advantages. METHODS: All randomized controlled trials (RCTs) and cohort studies assessing the two access sites, IJV and SCV, were retrieved from PubMed, Web of Science, Embase, and OVID EMB Reviews from their inception to December 2015...

Preeclampsia is a hypertensive disorder of pregnancy that has limited therapeutic options. In healthy pregnancy, relaxin plays an important vasodilatory role to maintain vascular compliance; however, currently, there is no preclinical evidence to support the use of relaxin during preeclampsia. Therefore, the goal of this study was to test the hypothesis that recombinant human relaxin-2 (Serelaxin, Novartis; RLX) could reduce mean arterial pressure (MAP) and improve uterine artery resistance index (UARI) and nitric oxide bioavailability, and/or decrease prepro-endothelin-1 (PPET-1), soluble fms-like tyrosine kinase-1 (sFlt-1), and TNF-α) in the reduced uterine perfusion pressure (RUPP) model of preeclampsia...

INTRODUCTION: Stent delivery failure may occur especially when treating complex coronary artery stenosis. XLIMUS (CARDIONOVUM GmbH, Bonn, Germany) is a new sirolimus-eluting stent (SES) with the following features: 1) cobalt chromium stent platform, with low (73 μm) strut thickness, (2) biodegradable polymer, and 3) potent antiproliferative drug (Sirolimus). Preliminary data suggest that XLIMUS SES may be ideal for the treatment of complex lesions. METHODS: In this registry, we assessed the deliverability, safety, and efficacy of percutaneous coronary interventions (PCI) using the XLIMUS SES in patients undergoing elective PCI in native coronary vessels for complex de novo lesions, including severe calcification, severe tortuosity, and chronic total occlusion...
