Characteristics, Risk Factors, and Outcome of New-onset Systolic Heart Failure After Liver Transplantation: A Single-center Cohort.

Unlabelled: New-onset systolic heart failure (HF) after liver transplantation (LT) is a significant cause of morbidity and mortality; however, its characteristics are still insufficiently delineated. HF may involve the left ventricle (LV), right ventricle (RV), or both ventricles. We explored the incidence, characteristics, etiologies, risks, involved cardiac chambers, and outcomes of HF after LT.

Multivisceral Transplant in a Patient With Portopulmonary Hypertension: A Case Report.

Portopulmonary hypertension, a type of pulmonary arterial hypertension in the setting of cirrhotic or noncirrhotic portal hypertension, is associated with elevated morbidity and mortality during and after transplantation. Uncontrolled portopulmonary hypertension may prevent or delay listing for transplant candidates, and the prognosis without treatment and ultimately transplant is extremely poor. We present a 29-year-old White woman, who had a post-liver transplant at infancy due to biliary atresia.

Occurrence and outcome of blood-contaminated percutaneous injuries among anesthesia practitioners: a cross-sectional study.

Background: Anesthesia practitioners are at risk for percutaneous injuries by blood-contaminated needles and sharp objects that may result in the transmission of human immunodeficiency virus and hepatitis viruses. Reporting these injuries is important for the early prevention and management of blood-borne infections.

Objective: To investigate the occurrence, reporting, characteristics and outcome of contaminated percutaneous injuries (CPIs) in anesthesia residents, fellows and faculty.

Perioperative risk factors associated with delayed graft function following deceased donor kidney transplantation: A retrospective, single center study.

Background: There is an abundant need to increase the availability of deceased donor kidney transplantation (DDKT) to address the high incidence of kidney failure. Challenges exist in the utilization of higher risk donor organs into what appears to be increasingly complex recipients; thus the identification of modifiable risk factors associated with poor outcomes is paramount.

Aim: To identify risk factors associated with delayed graft function (DGF).

Thrombotic and hemorrhagic complications during visceral transplantation: risk factors, and association with intraoperative disseminated intravascular coagulation-like thromboelastographic qualities: a single-center retrospective study.

This study describes the risk of thrombotic and hemorrhagic complications, both intraoperatively, and up to 1 month following visceral transplantation. Data from 48 adult visceral transplants performed between 2010 and 2017 were retrospectively studied [32 multivisceral (MVTx); 10 isolated intestine; six modified-MVTx]. Intraoperatively, intracardiac thrombosis (ICT)/pulmonary embolism (PE) occurred in 25%, 0% and 0% of MVTx, isolated intestine and modified MVTx, respectively, and was associated with 50% (4/8) mortality.

Stuck bioprosthetic aortic valve--a new entity? A case report.

We describe herein a case of bioprosthetic valve malfunction, which closely imitates a stuck valve. Although the term "stuck" was used originally for the immovable mechanical valve leaflets, the echocardiographic manifestation of this malfunction is similar to those of a mechanical one. The clinical presentation of the stuck bioprosthesis is, however, far more benign than a stuck mechanical valve.

Cardiac troponin after major vascular surgery: the role of perioperative ischemia, preoperative thallium scanning, and coronary revascularization.

Objectives: We sought to determine the role of preoperative predictors, particularly ischemia, on preoperative thallium scanning (PTS) and coronary revascularization on low-level and conventional troponin elevations after major vascular surgery.

Background: Postoperative cardiac troponin (cTn) elevations have recently been shown to predict both short- and long-term mortality after vascular surgery.

Methods: The perioperative data, including PTS and subsequent coronary revascularization, continuous perioperative 12-lead ST-segment trend monitoring, cTn-I and/or cTn-T, and creatine kinase-MB fraction in the first three postoperative days, were prospectively collected in 501 consecutive elective major vascular procedures.

Association of cardiac troponin, CK-MB, and postoperative myocardial ischemia with long-term survival after major vascular surgery.

Objectives: The aim of this study was to determine the long-term prognosis with postoperative markers of myocardial ischemia and infarction.

Background: Cardiac troponins (cTn) are superior to creatine kinase-MB fraction (CK-MB) in detecting perioperative myocardial infarction (PMI). However, their threshold levels signifying PMI and their long-term prognostic value are not yet determined.

Pharmacokinetics and metabolism of ryodipine in rats.

2,6-Dimethyl-3,5-dimethoxycarbonyl-4-(o-difluoromethoxyphenyl)-1, 4-dihydropyridine (ryodipine, PP-1466) at oral administration in the form of a suspension with Tween (polysorbate) 80 addition is comparatively rapidly absorbed in the gastro-intestinal tract and circulates in blood for a long period of time. PP-1466 practically does not bind to plasma proteins. The drug is mainly excreted via the kidneys and with faeces by 49 and 46% of the dose administered after 96 h, respectively.

Preparation and properties of ryodipine, an effective antihypertensive agent.

A novel effective antihypertensive agent, 2,6-dimethyl-3,5-dimethoxycarbonyl-4-(o-difluoromethoxyphenyl++ +)-1,4-dihydropyridine (ryodipine, PP-1466) has been obtained. A method for ryosidine synthesis has been developed, side products of PP-1466 synthesis have been isolated and identified. Special characteristics (IRS, UVS, NMR, MS) and chromatography data (TLC, HPLC) are cited.
