Multi-Task Transfer Learning (MTTL) is an efficient approach for learning from inter-related tasks with small sample size and imbalanced class distribution. Since the intensive care unit (ICU) data set (publicly available in Physionet) has subjects from four different ICU types, we hypothesize that there is an underlying relatedness amongst various ICU types. Therefore, this study aims to explore MTTL model for in-hospital mortality prediction of ICU patients. We used single-task learning (STL) approach on the augmented data as well as individual ICU data and compared the performance with the proposed MTTL model...

BACKGROUND: Allogeneic red blood cell (RBC) transfusion has been associated with new-onset postoperative atrial fibrillation (POAF) following cardiac surgery. Prolonged storage time of RBC may increase the risk. The primary aim of the study was to evaluate whether the storage time of RBC is associated with development of POAF. MATERIALS AND METHODS: Pre-, per- and postoperative data were retrieved from the Western Denmark Heart Registry and local blood banks regarding patients who underwent coronary artery bypass surgery, valve surgery or combined procedures in Aalborg or Aarhus University Hospital during 2010-2014...

Objective: To evaluate whether brachial artery peak velocity variation(ΔVp) during a Valsalva maneuver(VM) could predict fluid responsiveness in spontaneously breathing patients. Methods: Ninety-six patients required radial artery catheter for elective surgery of Ningbo Yinzhou People's Hospital from December 2014 to June 2016 were enrolled. The brachial artery Doppler signal was recorded to measure the ΔVp while the VM was performed.Then doing the volume expansion (VE) , the cardiac output variation (ΔCO) before and after VE were measured...

BACKGROUND: Even mild and transient acute kidney injury (AKI), defined by increases in serum creatinine level, has been associated with adverse outcomes after major surgery. However, characteristic decreases in creatinine concentration during major illness could confound accurate assessment of postoperative AKI. METHODS: In a single-hospital, retrospective cohort study of non-cardiac surgery, the association between postoperative AKI, defined using the Kidney Disease: Improving Global Outcomes criteria, and 1-year survival was modelled using a multivariable Cox proportional hazards analysis...

Epinephrine, a non-specific adrenergic agonist, is one of the most commonly used inotropes perioperatively. Recent studies have shown that inflammatory response in cardiac surgery could result in hypoperfusion, dysrhythmias, myocardial ischemia, and other pathophysiological alterations in the postoperative period. These alterations might be contributing to the adverse clinical outcome. Although epinephrine has been shown to have effects on the immune system, how epinephrine affects inflammatory response is unclear...

The evaluation of the vast majority of children with anomalous aortic origin of a coronary artery (AAOCA) and/or myocardial bridges is performed with non-invasive testing. However, a subset of these patients may benefit from invasive testing for risk stratification. All patients included in the Coronary Anomalies Program (CAP) at Texas Children's Hospital who underwent cardiac catheterization were included. Techniques included selective coronary angiograms (SCA), intravascular ultrasound (IVUS), and fractional flow reserve (FFR) measurements with provocative testing using adenosine and/or dobutamine infusions...

OBJECTIVES: We sought to assess the feasibility and safety of same-day discharge (SDD) after complex percutaneous coronary intervention (PCI) using a forearm approach. BACKGROUND: SDD has been shown to be safe after elective, low-risk PCI. However, the feasibility and safety of SDD in more complex patients and lesions has received limited study. METHODS: We retrospectively reviewed 1190 elective PCIs that were performed between January 2013 and December 2015 at the Red Cross General Hospital...

A consistent message within critical care publications has been that a restrictive transfusion strategy is non-inferior, and possibly superior, to a liberal strategy for stable, non-bleeding critically ill patients. Translation into clinical practice has, however, been slow. Here, we describe the degree of adherence to UK best practice guidelines in a regional network of nine intensive care units within Wessex. All transfusions given during a 2-month period were included (n = 444). Those given for active bleeding or within 24 h of major surgery, trauma or gastrointestinal bleeding were excluded (n = 148)...

To assess the significance of an analogue of the mean systemic filling pressure (Pmsa) and its derived variables, in providing a physiology based discrimination between responders and non-responders to fluid resuscitation during liver surgery. A post-hoc analysis of data from 30 patients undergoing major hepatic surgery was performed. Patients received 15 ml kg(-1) fluid in 30 min. Fluid responsiveness (FR) was defined as an increase of 20% or greater in cardiac index, measured by FloTrac-Vigileo(®). Dynamic preload variables (pulse pressure variation and stroke volume variation: PPV, SVV) were recorded additionally...

INTRODUCTION: Cancer of the esophagus is among the leading cause of cancer deaths in Punjab, India. Patients generally present with dysphagia as their first symptom and more often they have advanced disease at the time of presentation to a tertiary care centre. Palliative procedures have important roles in this setting. Stenting is the best option to palliate the symptoms of dysphagia, from which patient is suffering the most. AIM: To know the success rate, early and long term complications and mortality in esophageal stenting, when it was done in malignant esophageal stricture patients...

There is an ongoing investigation into infections with non-tuberculous mycobacteria associated with contaminated heater-cooler units used in cardiac surgery. The overall risk is low, but surgical site and disseminated infections have been reported, including one possible case in Australia, mainly with surgery involving implantation of prosthetic material. Mycobacterium chimaera infection should be considered in patients who have previously undergone surgery with cardiopulmonary bypass and who present with cardiac or disseminated infection or sternal wound infection unresponsive to standard antibiotic therapy...

Two cases of patients that developed right ventricular failure (RVF) after cardiac valve surgery are presented with a narrative revision of the literature. RVF involves a great challenge due to the severity of this condition; it has a low incidence among non-congenital cardiac surgery patients, is more likely associated with cardiovascular and pulmonary complications related to cardiopulmonary bypass (CPB), and is a cause of acute graft failure and of a higher early mortality in cardiac transplant. The morphologic and hemodynamic characteristics of the right ventricle and some specific factors that breed pulmonary hypertension after cardiac surgery are in favor of the onset of RVF...

OBJECTIVES: In a recent consensus statement on early pregnancy nomenclature by Barnhart 2011, a definite ectopic pregnancy(EP) was defined morphologically on transvaginal ultrasound (TVS) as an extra-uterine gestational sac(GS) with yolk sac and/or embryo(with or without cardiac activity) whilst a probable EP defined as an inhomogeneous adnexal mass("blob" sign) or extra-uterine sac-like structure("bagel" sign). This study aims to determine whether the ultrasound markers used to define probable EP can be used to predict a definite tubal EP...

BACKGROUND: Successful percutaneous mitral valve repair (PMVR) in patients with severe mitral regurgitation (MR) causes changes in hemodynamics. Echocardiographic calculation of cardiac output (CO) has not been evaluated in the setting of PMVR, so far. Here we evaluated hemodynamics before and after PMVR with the MitraClip system using pulmonary artery catheterization, transthoracic (TTE) and transesophageal (TEE) echocardiography. METHODS: 101 patients with severe MR not eligible for conventional surgery underwent PMVR...

Dual antiplatelet therapy (DAPT) consisting of aspirin plus a P2Y12 inhibitor (clopidogrel, prasugrel, or ticagrelor) is imperative for the treatment of acute coronary syndrome, particularly during the re-endothelialization period after percutaneous coronary intervention (PCI). When patients undergo surgery during this period, the consequences of stent thrombosis are far more serious than those of bleeding complications, except in cases of intracranial surgery. The recommendations for perioperative DAPT have changed with emerging evidence regarding the improved efficacy of non-first-generation drug (everolimus, zotarolimus)-eluting stents (DES)...

In recent years, US hospitals have switched from use of unfractionated heparin to use of low-molecular-weight heparin, which is associated with lower risk of heparin-induced thrombocytopenia (HIT). In the study reported here, we retrospectively searched the Nationwide Inpatient Sample (NIS) for patients who were at least 18 years old and received a diagnosis of HIT between 2009 and 2011. Our goal was to get an updated perspective on the incidence and economic impact of HIT. We calculated the incidence of HIT overall and in subgroups of patients who underwent cardiac, vascular, or orthopedic surgery...

PURPOSE: Despite recent advancements in the use of thrombelastography (TEG) in the surgical setting, adequate technology to accurately predict bleeding phenotypes for patients undergoing cardiopulmonary bypass on the basis of non-mechanical parameters is lacking. While basic science and translational studies have provided key mechanistic insights about the protein components of coagulation cascades and regulatory mediators of hemostasis and fibrinolysis, targeted protein assays are still missing and the association of protein profiles to bleeding phenotypes and TEG readouts have yet to be discovered...
