BACKGROUND: Postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) may complicate a patient's postoperative recovery in several ways. Monitoring of processed electroencephalogram (EEG) or evoked potential (EP) indices may prevent or minimize POD and POCD, probably through optimization of anaesthetic doses. OBJECTIVES: To assess whether the use of processed EEG or auditory evoked potential (AEP) indices (bispectral index (BIS), narcotrend index, cerebral state index, state entropy and response entropy, patient state index, index of consciousness, A-line autoregressive index, and auditory evoked potentials (AEP index)) as guides to anaesthetic delivery can reduce the risk of POD and POCD in non-cardiac surgical or non-neurosurgical adult patients undergoing general anaesthesia compared with standard practice where only clinical signs are used...

Human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) are emerging tools for applications such as drug discovery and screening for pro-arrhythmogenicity and cardiotoxicity as leading causes for drug attrition. Understanding the electrophysiology (EP) of hPSC-CMs is essential but conventional manual patch-clamping is highly laborious and low-throughput. Here we adapted hPSC-CMs derived from two human embryonic stem cell (hESC) lines, HES2 and H7, for a 16-channel automated planar-recording approach for single-cell EP characterization...

OBJECTIVES: To determine whether there is an association between morphologic types of tubal ectopic pregnancy (EP), 0-hour human chorionic gonadotropin (hCG) levels, and subsequent management success. METHODS: We conducted a prospective study (November 2006-December 2015). Women had a diagnosis of EP by transvaginal ultrasonography if they had an inhomogeneous mass adjacent to the ovary and moving separately from it ("blob" sign), a mass with a hyperechoic ring around the gestational sac ("bagel" sign), or a gestational sac with an embryonic pole with or without a yolk sac with or without cardiac activity...

PURPOSE OF REVIEW: There is growing awareness of the link between oncology treatments and cardiovascular (CV) complications. This has led to the development of cardio-oncology, a specialty aimed at managing CV risk and disease in cancer patients and survivors. Cardiac arrhythmias are potential adverse CV complications of cancer treatments; however, these cardiotoxicities are often underappreciated due to the uncertain arrhythmogenic mechanisms of various chemotherapeutic agents. RECENT FINDINGS: Chemotherapeutic agents can induce arrhythmias via direct electrophysiological effects on ion channels or intracellular signaling pathways, or indirectly from cardiac tissue damage...

Cardiac simulations play an important role in studies involving understanding and investigating the mechanisms of cardiac arrhythmias. Today, studies of arrhythmogenesis and maintenance are largely being performed by creating simulations of a particular arrhythmia with high accuracy comparable to the results of clinical experiments. Atrial fibrillation (AF), the most common arrhythmia in the United States and many other parts of the world, is one of the major field where simulation and modeling is largely used...

Background: Premature ventricular beats (PVBs) are early depolarization of the myocardium originating in the ventricle. In case of very frequent PVBs, patients are severely symptomatic with impaired quality of life and are at risk of pre-syncope, syncope, heart failure, and sudden cardiac death particularly in the presence of structural heart disease. Ventricular outflow tracts are the most common sites of origin of idiopathic PVBs especially in patients without structural heart disease...

PURPOSE: In cardiac electrophysiology, a long and flexible catheter is delivered to a cardiac chamber for the treatment of arrhythmias. Although several robot-assisted platforms have been commercialized, the disorientation in tele-operation is still not well solved. We propose a validation platform for robot-assisted cardiac EP catheterization, integrating a customized MR Safe robot, a standard clinically used EP catheter, and a human-robot interface. Both model-based and model-free control methods are implemented in the platform for quantitative evaluation and comparison...

PURPOSE: Cardiomyopathies frequently lead to conduction system disease and/or arrhythmias necessitating device therapy, catheter ablation, or both. Endomyocardial biopsy (EMB) is avoided with recent right ventricle (RV) lead implants and optimal timing is uncertain. We determined outcomes of EMB at the time of ablation or device implantation procedures. METHODS: We retrospectively analyzed patients undergoing EMB during their electrophysiological procedure between January 2014 and July 2016...

Cardiac implantable electronic device (CIED) infections are associated with significant morbidity in the pediatric device population, with a tenfold higher risk of infection in children compared to adults. The 2010 American Heart Association (AHA) guidelines recommend a single dose of systemic antibiotic (ABX) prophylaxis prior to CIED implantation and no post-operative (OP) ABX. However, there is limited data regarding adherence to this recommendation among the pediatric community. To assess current clinical practices for CIED ABX prophylaxis in pediatrics; whether the AHA guidelines are being followed; and if not, the reasons for non-adherence...

M Roessler, N Eulitz
The scope of emergency calls for emergency medical services staffed by an emergency physician (EMS-EP) includes calls to patients with life-limiting diseases. Symptom exacerbation as well as psychosocial overburdening of caring relatives are the most frequent reasons for activation of an EMS-EP. Pain crises, acute dyspnea, massive bleeding and/or an impending or overt cardiac arrest are the most frequent symptom exacerbations. Under the conditions of a prehospital emergency physician mission, particular challenges are the evaluation of the overall situation, the prognosis and the presumed will of the patient...

INTRODUCTION: Appropriate mechanical ventilation and prevention of alveolar collaps is mainly dependent on transpulmonary pressure TPP. TPP is assessed by measurement of esophageal pressure EP, largely influenced by pleural and intraabdominal pressure IAP. Consecutively, TPP-guided ventilation might be particularly useful in patients with high IAP. This study investigates the impact of large volume paracentesis LVP on TPP, EP, IAP as well as on hemodynamic and respiratory function in patients with liver cirrhosis and tense ascites...

Invasive electrophysiology (EP) mapping and catheter ablation has increasingly become the standard of care for many cardiac arrhythmias like supraventricular tachycardias, atrial fibrillation, premature ventricular complexes (PVC), and monomorphic ventricular tachycardia. In this review, we discuss the recent progress made in the mapping and ablation of ventricular fibrillation (VF). Ventricular activation during VF is apparently disorganized, making mapping and interpretation difficult. Prolonged mapping during VF would require mechanical circulatory support as VF causes complete hemodynamic collapse...

PURPOSE: To describe our magnetic resonance imaging (MRI) simulated implementation of the 4D digital extended cardio torso (XCAT) phantom to validate our previously developed cardiac tracking techniques. Real-time tracking will play an important role in the non-invasive treatment of atrial fibrillation with MRI-guided radiosurgery. In addition, to show how quantifiable measures of tracking accuracy and patient-specific physiology could influence MRI tracking algorithm design. METHODS: Twenty virtual patients were subjected to simulated MRI scans that closely model the proposed real-world scenario to allow verification of the tracking technique's algorithm...

Activation of renin-angiotensin system (RAS) is one of the pathological mechanisms associated with myocardial ischemia-reperfusion injury following resuscitation. The present study aimed to determine whether erythropoietin (EPO) improves post‑resuscitation myocardial dysfunction and how it affects the renin‑angiotensin system. Sprague‑Dawley rats were randomly divided into sham, vehicle, epinephrine (EP), EPO and EP + EPO groups. Excluding the sham group, all groups underwent cardiopulmonary resuscitation (CPR) 4 min after asphyxia‑induced cardiac arrest (CA)...
